Afghan demonstrators blocked the path of a U.S. military convoy in eastern Afghanistan on Saturday after an overnight U.S. raid killed four Afghans and wounded two, an official and protesters said. Protesters in the eastern city of Khost threw rocks at the convoy. Several hundred men gathered in the street, preventing the vehicles from passing. The demonstrators were condemning an early morning raid in Khost province that killed four people and wounded two, said Tahir Khan Sabari, Khost deputy governor. Protesters also said several Afghans were arrested in the raid, according to a report of Associated Press. Sabari said the four killed were civilians.
