NATO says coalition troops are working to recover every last piece of a Chinook helicopter that crashed over the weekend, killing 30 American troops, seven Afghan soldiers and an Afghan interpreter.
German Brig. Gen. Carsten Jacobson, a spokesman for the U.S.-led coalition, told reporters at a briefing Monday that troops have secured the crash site in Wardak province and nobody is being allowed in or out of the area while the investigation is ongoing.
Jacobson says the coalition still has not determined the exact cause of the crash.
It was deadliest single incident for U.S. forces in the decade-long war.
Several U.S. officials have said that insurgents apparently shot down the Chinook on Saturday as it rushed in to reinforce Army Rangers who had come under fire.
More details are emerging about the helicopter crash in Afghanistan that claimed the lives of 38 people, 30 of whom were Americans, 22 of them elite Navy SEALs.
Two U.S. officials say the American troops had just completed a rescue mission to help a U.S. Army Ranger unit that was under fire.
They were leaving in their Chinook when the aircraft was apparently hit by insurgent fire. All on board were killed, making it the deadliest single loss for U.S. forces in the decade-long war in Afghanistan.
Today, NATO began an operation to recover the remains of the large transport helicopter, while Afghan and American forces battled insurgents in the region of the crash.
Elsewhere in Afghanistan, NATO said insurgents killed four alliance service members in two separate attacks in the east and the south. It did not provide their nationalities or any other details.
