Kabul rocked by suicide bombing that killed at least 28

A Taliban suicide bomb and gun assault on a government security building during morning rush hour in central Kabul killed at least 28 people and wounded more than 320, in the most deadly single attack in the Afghan capital since 2011.

President Ashraf Ghani condemned the assault “in the strongest possible terms” in a statement from the presidential palace, located a few hundred metres away from the scene of the blast.

The insurgency led by the Afghan Taliban has gained strength since the withdrawal of most international combat troops at the end of 2014, and the Islamist group is believed to be stronger than at any point since it was driven from power by US-backed forces in 2001.
