Taliban gunmen disguised in women’s burqas and wearing military uniforms underneath stormed a court building in an eastern Afghan province on Wednesday, killing five civilians and a policeman, Afghan officials said.

A statement from the Interior Ministry said “four terrorists” were involved in the attack in the city of Ghazni, the capital of the eastern Ghazni province.

Jawed Salangi, spokesman for the provincial governor, said a suicide bomber launched the coordinated attack by blowing himself up at the court’s entrance, after which three other attackers stormed the building.

The ministry said a firefight ensued and the three other attackers were shot and killed by the security forces. Salangi said police were also attempting to defuse an explosives-packed vehicle parked near the courthouse.
