Five US troops were killed in attacks in southern Afghanistan, where the US and NATO have ramped up operations against the Taliban and seen casualties rise quickly in what has been the deadliest year of the war for international forces.
Four soldiers died Thursday in the same small district of Zabul province, including three killed when their Stryker vehicle struck a bomb, said US military spokesman Lt. Robert Carr. The fourth was shot to death in an insurgent attack, Carr said.
The Stryker brigade in Zabul is part of the influx of US troops sent by President Barack Obama over the summer to try to reverse Taliban gains.
A US Marine was fatally shot while on foot patrol in Nimroz province and died Thursday, said Capt. Elizabeth Mathias, a military spokeswoman.
The deaths come as the Obama administration debates whether to send still more forces to Afghanistan.
