Asadabad, Afghanistan, April 1, SPA -- A blast hit a U.S. military convoy in Afghanistan on Saturday but there were no immediate reports of casualties, Afghan provincial officials said. The explosion happened in the Peche valley of eastern Kunar province, near the border with Pakistan and the scene of repeated clashes between insurgents and U.S. and Afghan government troops. A helicopter was seen landing in the area soon after the blast, leading to speculation it may have been evacuating casualties, said one official, who declined to be identified. A U.S. military spokesman said he had no report on the blast, which was in the same area where four U.S. soldiers were killed by a roadside bomb last month, according to a report of Reuters. --SPA 14 44 Local Time 11 44 GMT www.spa.gov.sa/350092
