Kabul (Reuters): Dozens of people were killed or wounded when as many as five suicide bombers attacked a police headquarters in eastern Afghanistan on Sunday, officials said.

The attack , claimed by the Taliban, began around 6:30 am when one bomber detonated a car packed with explosives at the gate of the police headquarters in Gardez city, capital of Paktia province, said Najib Danish, a spokesman for the Interior Ministry.

Four more attackers stormed the gate after the blast, with at least two quickly killed by police . The others held out against Afghan special forces that had responded to the attack , he said.

Danish put the toll at two police killed and five wounded .

However, doctors at the city hospital said they had received the bodies of at least five police , as well as at least 30 wounded people, including 20 civilians.

The Taliban claimed responsibility for the attack , with spokesman Zabihullah Mujahid reporting more than 100 police were killed and wounded . The Islamist group often exaggerates casualty numbers in attacks against government targets and security forces.
