Two US troops missing in Afghanistan have been found dead.
Another was rescued on Saturday, and the fate of a fourth remains unknown.
The team of US troops was reported missing last Tuesday in Kunar province. A rescue effort the same day failed when the helicopter seeking to extract the team was shot down, killing 16 troops aboard.
The serviceman rescued on Saturday had taken shelter in an Afghan village elder's home in the province before US forces were notified of his location and picked him up, the Kunar provincial governor said.
A purported Taliban spokesman claimed last week that militants had captured one team member. He said the "high-ranking American" was caught in the area where the helicopter went down.
Elsewhere, a US airstrike in Afghanistan's rugged eastern mountains killed 17 civilians, including women and children, an Afghan official said. The US military confirmed civilian deaths but said the numbers were unclear.
An initial airstrike destroyed a house, and as villagers gathered to look at the damage, a US warplane dropped a second bomb on the same target, the Kunar governor said.
