KABUL, Afghanistan (CNN) -- At least five people were killed when a helicopter went down in southern Afghanistan's Helmand province Tuesday, a local government official said.
A U.S. helicopter delivers supplies for a convoy in Afghanistan's Helmand Province on Saturday.
The helicopter was providing food and supplies to the NATO forces in Helmand, where thousands of U.S. and British forces are leading separate offensives against militants throughout the province -- a Taliban stronghold and poppy-growing region.
Haji Fazul Haq, district governor of Sangin District, said one of the five was an Afghan and the rest were foreigners.
A Taliban spokesman said the militant group shot down an aircraft and had killed 37 foreign soldiers. Taliban claims have often turned out to be exaggerated under similar circumstances.
