KHOST, Afghanistan (Reuters) -- A suicide bomb has hit a convoy of NATO-led troops and killed two soldiers in southeastern Afghanistan.
Another soldier was wounded by the blast, which happened in Khost Province near the border with Pakistan, said a spokesman for the International Security Assistance Force (ISAF).
The Afghan Interior Ministry said the blast was caused by a suicide bomb.
Most troops in eastern Afghanistan are American.
Afghanistan is in the grip of the worst violence since the Taliban were toppled from power in late 2001.
Taliban insurgents and their allies have made a comeback in the last two years in their campaign to drive out foreign forces and topple the Afghan government.
