A passenger truck ran off the road in a remote mountainous region of Afghanistan on Wednesday, killing 15 people and wounding 56, an official said. Three suicide bomb attacks around the country killed one person. The truck ran off the road in the northeastern province of Badakhshan. President Hamid Karzai ordered Afghan army helicopters to help evacuate the wounded to better hospitals in Kabul, the capital, but bad weather was hindering that effort, said Abdul Mamoon Jalali, the provincial health director. In the eastern province of Khost, meanwhile, two suicide bombers tried to attack a US military outpost but were stopped by Afghan police at a checkpoint. Police opened fire and killed both bombers, said Gen. Mohammad Ayub, the provincial police chief. He said no one else was killed. A US spokesman said he didn't immediately have any information about the incident. In Helmand province, a suicide bomber on a motorbike targeted a police truck but missed, said Doulad Wazir, the governor's spokesman. One civilian was killed, he said.
