Afghanistan: Bomb kills 2 US troops; NATO losses at 23 for June

Two more American troops were killed in Afghanistan on Tuesday, the military said, extending a spike of bloodshed into a second day and pushing the NATO losses in the country to 23 in just over a week.

The latest deaths came as insurgents step up bombings and other attacks ahead of a major NATO operation in the Taliban stronghold of Kandahar that Washington hopes will turn the tide of the nearly 9-year-old war. (AP)
