A bomb blast exploded outside the main U.S. base in Afghanistan on Wednesday, wounding several people, a U.S. official said. An Afghan governor blamed the attack on a suicide car bomber, and the Taliban claimed responsibility, according to a report of Associated Press. The blast outside the main base at Bagram did not appear to kill anyone, according to early reports, said Capt. Elizabeth Mathias, a U.S. spokeswoman. The governor of Parwan province, Abdul Jabar Takwa, said the bomber was in a car that exploded after he drove past a police checkpoint. Bagram is in Parwan province. Takwa said that the bomber died in the blast, but he did not have any other casualty reports.
