Thousands of economic migrants are trying to claim asylum to reach Europe. But there are claims the rising numbers are making Europe a more dangerous place to be, with violence rife in migrant camps. This week, David Cameron said Europe must send failed asylum claimants back to their own countries, while European Council president Donald Tusk has warned that millions more migrants are on their way and 'the policy of open doors and windows' must be scrapped. They are tough words, but it's action that is needed.

The 'rainbows' (left and right) are actually circumzenthial arcs, and form when light refracts through ice crystals found in thin clouds, meaning they formed in the sky over New York today despite there being no rain. The halos of color were spotted by around 80,000 people waiting near Central Park and Madison Square Garden as Francis traveled through this afternoon (inset) before giving Mass. People took to Twitter to post the images, alongside the hashtag 'blessed'.

Around 80,000 people lucky enough to have tickets lined Central Park as Pope Francis continued his whirlwind American tour, but pictures from the scene appeared to show thousands more men, women and children gathering to get a glimpse of him. The Pope has since arrived at Madison Square Garden to a monumental roar from the 20,000 people gathered to see him lead a huge mass. The Pontiff was met by trumpets and fanfare as he entered the arena, stopping to bless a special needs child whose parents openly wept as Francis showed his affection.

Police arrested an Oregon mother for allegedly killing her son in the home they shared on Thursday. Dianne M. Davidoff was arrested and charged with the murder of her 17-year-old son Jacob Ryan Davidoff. The teenager was shot in the back at the family's home on Rosefinch Drive in Gresham.

Duck Dynasty star Willie Robertson has backed Donald Trump after the billionaire brandished his childhood Bible and vowed to reclaim Christmas. The reality TV star said he 'liked me some Trump' after the Republican presidential candidate called him up to the stage at the Oklahoma State Fair. Trump had earlier said he was fed up of people saying 'happy holidays' instead of 'merry Christmas' and insisted this would change if he comes to power.

Twenty years after O.J. Simpson was found not guilty for the murder of his ex-wife Nicole Brown, Kris Jenner is reflecting on what she could have done to save her late best friend. The 59-year-old appears in new LMN documentary The Secret Tapes of the O.J. Case: The Untold Story, in which she recalls how Nicole would share her fears that the football star and actor could hurt her. 'At the end of Nicole's life, I think she finally was at a place where she knew she had to be more vocal with what was going on and she was in trouble,' Kris said, according to ABC News.

Researchers in Australia say that people can tell a love cheat from just their face 59 per cent of the time - so look at these twelve people and see whether you think they are faithful or not. Among these faces are a self-confessed philanderer and lovers who were bored, drunk or just reckless. Some of them ruined their relationships for ever - while others were forgiven and are still with their partners today.

Abigail Hall's sudden death was broken to her boyfriend Josh Thompson (pictured together, left) while he was working as a tennis coach in the Greek island of Corfu. He immediately flew home to her family in Doncaster and asked for their permission to propose. They agreed to the unusual step and he bought her an engagement ring. He then popped the question privately, placing the wedding band over the 18-year-old's finger and posting a photograph on Facebook (right) with the heartbreaking message: 'Abigail Hall and I are now engaged. She is my life.'

Rachael Lilienthal, 37, (right) said when the alligator bit on her right arm in Wekiva River, Florida, she had to touch its head with her left hand to make sure she wasn't dreaming. The 9ft-long gator chewed off her limb and swam away after kayakers hit it with their paddles. Rachael, who lives in Florida, said they saved her life, as did a man who pulled her from the water by her remaining arm. Her blood was smeared over the kayaks (left) following the attack.

Dressed in his blacks, the Lord Commander of the Night's Watch, was standing tall with his sword on his hip as they filmed on the remote Northern Ireland hilltop on Friday. Kit, who has been spotted in Belfast on several occasions over the past few weeks, was surrounded by several members of the crew as they took a break between scenes.

A massive high school football player is focused on making his way into the NFL. John Krahn is just 17-years-old, but is 7-feet tall and weighs in at 440 pounds, making him the biggest high school player in the country. He would also become the tallest player in NFL history should he be drafted into the league - and as a lineman near impossible to block or get past.

Terricka Cromartie (left) was stopped around 11.30am in the town of Madison, New Jersey, which is located just over 30 miles away from where NFL cornerback Antonio Cromartie (inset) plays for the Jets in East Rutherford. Cromartie assumed the officer (right) stopped her because of the color of her skin and wrote he pulled her over for 'no reason' so he could ask her to roll down her windows and ask why she was in Madison. She posted a video of the incident and her reaction on Instagram.

MacKenzie Walker weighed 223 pounds when she started eighth grade and started dieting after she had to buy a size 22 dress for her school prom. 'Thoughts started rolling in about dying, of not waking up one morning,' she admitted. The plucky teenager has been sharing 'before' and 'after' photos from her incredible weight-loss journey on Instagram (left and right), where she has 60,000 Instagram fans - as well as pictures of her weight-training (inset).

Alejandro Gomez Monteverde, husband of former Miss USA Ali Landry, was seen in Los Angeles outside his family home for the first time since his relatives were killed. Father Juan Manuel Gomez Fernandez and brother Juan Manuel Gomez Monteverde are believed to have gone missing in Mexico on September 9 in a suspected cartel kidnapping, before their bodies were found on Saturday. Despite the tragedy, Monteverde appeared to be in good spirits today.

The Sweetheart Rink was the place to be in downtown Tampa when photographer Bill Yates, then 26, stumbled upon it during his final year of college at the University of South Florida. 'That was big time, going to the skating rink,' he says. 'You had the Women's Movement and the Civil Rights movement. You had Vietnam raging. You had the hippies. You had sex, drugs and rock and roll. Music was changing dramatically. All that stuff from California had moved east.' By the summer of 1973, Yates had become as commonplace at Sweethearts as Pepsi cola and cigarettes, and had taken 800 photos, but they had sat in a box for over 30 years. Until now.

Dashcam footage captured the horrifying moment two police officers drew their guns on a husband and wife (right) after pulling them over while they were rushing to the hospital to give birth. James Reiner was driving his wife Dana (bottom left with her two daughters in 2014) to the hospital after her water broke in January 2012 in Hebron, Indiana when they passed a police car that suddenly turned on its lights to get the car to the side of the road, despite the fact that they were not speeding. That is when James got out to tell Sgt. Anthony Dandurand (top left) that his wife was pregnant and they needed to get to the hospital, which he responded to by cuffing the man on the ground while another officer, Travis Thomas, held a gun on James. Dana then tried to show the men that her water had indeed broke - and they pointed a gun directly at her belly and yelled at her to 'get back in the fu**ing car.'

The unnamed 59-year-old housewife from Maryland died of a heart attack 20 years ago and her body was donated by her husband to a project to create the most detailed digital model of a human. Her body was painstakingly scanned and reconstructed online. The digitised images reveal her internal organs (left), tissue, fat, brain (top right) and even the tiny bones in her feet (bottom right). It is allowing researchers to conduct dangerous experiments that would not be possible in living humans. In one example, they modeled what would happen to the body with a metal hip implant in the powerful magnetic field of an MRI scanner.

Rutgers University philosophy professor Anna Stubblefield, 45, insisted under cross-examination that she and the victim - a 34-year-old African-American man identified by his initials, D.J., who is unable to speak or eat on his own - were in a consensual relationship. On the second day of her rape trial, Stubblefield said from the stand that D.J. could communicate if he wanted to stop having sex in her Newark office in 2011 by banging on the floor. SHE IS pictured in court today, and at work, inset.

Dr Khurshid Guru (left), director of robotic surgery at the Roswell Park Cancer Institute in Buffalo, New York, used a plastic water bottle, a cup, some tape and an oxygen tank to piece together this makeshift nebulizer to administer oxygen and asthma medication to a sick 2-year-old boy on board a transatlantic flight September 18.

The Mountain Meadow reservoir (right), a body of water near Susanville, California also known as Walker Lake, was a popular spot for fishing before its 5,800 acres dried up the weekend of September 12. Thousands of dead fish (bottom left) then littered the muddy area where the lake used to be (left) before years of drought and residents were forced to deal with their foul smell. Pacific Gas and Electric, which owns the water rights to the lake, said that it did not open a dam to drain the lake and that the water simply left.

Dolce & Gabbana's Sicily bag is part of its Fall 2015 Viva La Mamma collection that celebrates motherhood. Trend for portraits appearing on handbags hit the mainstream when Kanye West gave wife Kim Kardashian a $40,000 Hermes bag hand-painted with a nude surrealist image.

With eight wheel drive and fitted with grenade launchers, the Amphibious Combat Vehicle is designed to carry up to 13 marines into combat. The firm behind it says future versions will even be able to drive themselves at sea. The ACV 1.1 is fully armoured, weighs over 20 tons and is powered by a 700 bhp six-cylinder turbodiesel engine. It can carry over 16,000 lb (7,200 kg) of payload, boasting upgradable sensors and communications, and can carry weapons ranging up to a 30-mm autocannon. It was inspired by the DUKW vehicles used in WWII (inset).

Their UC San Diego study found that, much like comedians, babies wait for the moment when their mother is at her most responsive before smiling. While mothers try to increase the time both parties are smiling, babies try to increase the time their mother smiles, while reducing their own effort in smiling, the researchers said. To confirm their findings, the researchers built the terrifying robot and programmed it to make humans smile.

The vacation snap of the little girl, who appears to be around four years old, has been viewed more than 1.4million times - and prompted a fierce debate. At first glance, the bright blue background of the water and the splashes around the child's face makes it look like she is swimming underwater. However, on closer inspection her hair - which is tied up in a cute ponytail - is dry, meaning just must have just jumped into a swimming pool.

A 60-year-old man has died in Russia, after his car collided with a lorry in an accident that has been blamed on a UFO (circled). Witnesses insisted that the two drivers were distracted by the mysterious object. Video footage shot by a dashboard camera in the car travelling behind captured the events that led up to the crash. Police are investigating but can offer no explanation for the object.

The incident took place in the south western city of Voronezh, where three weeks ago a pavement collapsed, leaving a huge hole in the ground. At some point between the hole appearing and workmen coming to fix it, the pregnant dog managed to crawl beneath the rubble. Staggeringly the builders were unaware of her presence when they sealed the crater, trapping the animal underground for two days without food or water.

The heartwarming moment was captured in a touching video that was then posted on the web. After the owner encourages the dog, Sheeta, to continue with the trick, she pushes the cradle back and forth while making eye contact with the baby. As the video proves, a paw can rock the cradle just as well as a hand.

Replica Statue of Liberty (left) was discovered in Dali, China, on September 24. It's in the gardens of an unidentified hotel and is 10 feet in height. The real version is over 305 feet tall (right). Knock-off architecture has been extremely popular in China in recent years, particularly for attracting tourists.

University in Wuhan, China, released an impressive military training video. Captured on September 23, footage showed 1,600 students forming numbers, characters and images. At the beginning of the video they did a rapid countdown (pictured) before moving on to spelling out Chinese characters and pictures with their bodies.
