WASHINGTON, May 18 (Xinhua) -- The growing death toll of Afghan civilians that resulted from U.S.-led military operations are endangering the Obama administration's strategy in that country, atop U.S. general conceded on Monday.
The killings of civilians during operations will "put our strategy in jeopardy," said Mike Mullen, chairman of the Joint Chiefs of Staff, at an event in the Brookings Institution, a Washington think-tank.
"We cannot succeed ... in Afghanistan by killing Afghan civilians," he added.
Mullen was referring to an incident in Afghanistan's Farah province on May 4, in which Afghan officials said some 147 civilians, including many women and children, were killed in a U.S.-led airstrike.
U.S. authorities haven't provided much details of the incident, but said an investigation is underway.
Mullen also said he hopes that with the recent influx of additional troops, the U.S. military will be able to "turn the tide" in Afghanistan in one to two years.
