A local Afghan official says a roadside bomb has killed four Afghan soldiers and their interpreter in Logar province south of Kabul.
Din Mohammad Darwesh, a spokesman for the province, says the soldiers were on a joint patrol with US forces on Tuesday when their vehicle hit a roadside bomb in Charkh district. Roadside bombs are the major cause of death and injury to US, NATO and Afghan forces deployed in Afghanistan.
Bombs killed 268 American troops in Afghanistan last year, a 60% increase over the previous year even as the Pentagon employs new measures to counter the Taliban's makeshift weapon of choice. Statistics for roadside bomb fatalities were not immediately available for Afghan National Security Forces.
