An Afghan official says Taliban gunmen have attacked a court building in eastern Ghazni province, killing at least one policeman, AP reported. Jawed Salangi, spokesman for the provincial governor, says a suicide bomber launched the coordinated attack by blowing himself up at the court's entrance, after which three other attackers stormed the building on Wednesday. He says two of the attackers were killed by security forces while the third is believed to remain inside the building. Salangi says police are also attempting to defuse an explosives-packed vehicle parked near the courthouse. The Taliban have claimed responsibility for the attack.
