New terror alert issued by US

The US government has warned of an increased risk of terror attacks on Americans at home and overseas, with a particular warning that al-Qaeda could try to hijack cargo jets and crash them into targets.

Terrorist bombings overseas and an increased volume of threats against US interests at home and in foreign countries led the Homeland Security Department and FBI to issue the public warning.

It said that "al-Qaeda's continued interest in aviation, including using cargo jets" to attack targets is of particular concern.

The warning added that "increased vigilance here at home is prudent and may be key to deterring or disrupting terrorist attacks".

The State Department also issued a "worldwide caution" for Americans travelling abroad, urging that they "maintain a high level of vigilance" for possible terrorist attacks.

But despite the warning, officials say there are no plans to raise the nation's colour-coded threat level beyond its current "yellow" position, the midpoint on a five-level scale.
