Militants launched a gun and bomb attack on the interior ministry in Kabul Wednesday, killing a policeman in the latest chilling demonstration of their ability to strike at the heart of the Afghan capital.

The attack during the holy month of Ramadan, claimed by the Islamic State group, was the latest deadly assault by the group in Kabul. Five people were injured.

The Taliban are also stepping up their attacks on the capital, making it the deadliest place in the country for civilians.

Special forces rushed to the scene after the attackers detonated what police said was a car bomb at the first checkpoint leading to the ministry, then tried to battle their way inside.

“The fighting is over, the attackers have all been killed by security forces between the first and second security perimeter,” said Kabul police chief Daud Amin.
