MEXICO CITY -- Mexico says it has sighted the remains of a Navy helicopter that went missing five days ago with four crew members aboard.

The Navy says the crash site has been found on a mountaintop in the western state of Jalisco, near the border with Michoacan state.

Emergency personnel are trying to reach the scene to determine the fate of the crew and the possible cause of the crash.

The Navy made the announcement late Tuesday.

The Eurocopter Panther helicopter set off from the Pacific coast city of Manzanillo Friday, headed for Morelia, the capital of Michoacan state. Military and law enforcement helicopters have been attacked with small arms fire in the area in the past.
