US soldier and two coalition troops killed in roadside bombing in Kabul, as attacks continue to escalate

Three NATO military personnel, including one American, were killed in a roadside car bombing in Kabul, Afghanistan on Friday. At least six civilians also died in the explosion which occurred while a convoy of armored vehicles was driving along a highway near Camp Phoenix, an American military base in Kabul. The Taliban claimed responsibility for the attack.

Over the last week and half, 13 NATO troops have been killed in Afghanistan.

The attack on Friday comes just two days after US diplomats and embassy staffers in the US embassy in Kabul were sent rushing to bomb shelters when rockets struck the US embassy compound.

The AP noted on Wednesday that "Afghan insurgents have increased attacks in recent months, intensifying a campaign to regain territory as foreign forces draw down ahead of full withdrawal at the end of 2014."
