250 Afghans in prison after riot in Kabul

A U.S. military spokesman, Col. Tom Collins said that an Afghan investigator will have "full access" to U.S. soldiers and equipment during the investigation into the crash. U.S. soldiers from the convoy involved in the accident will be made available for interviews.

Only about 1,000 people participated in the riot. Saleh, speaking at a separate news conference, said that some people were forced to participate by small gangs wielding guns.

Saleh said he could not yet say if a specific group - one opposed to the government of President Hamid Karzai, for instance - was behind the riot. He did say Afghan authorities had identified 10 people who led or encouraged the demonstrators, the AP reports.

Collins, who was also asked if a certain group was behind the riot, said officials "know for a fact that there were agitators in the crowd who worked to incite the crowd to get them riled up."

The crash, which killed up to five people and involved several cars, was caused by a U.S. military truck whose brakes failed, the U.S. military has said.
