An apparent suicide blast close to a government ministry in the Afghan capital Kabul on Sunday killed at least seven people and wounded more than 15, officials said, in an attack claimed by Islamic State.

The attack, which targeted civil servants leaving work in the evening rush hour, was the latest in a seemingly unending series of blasts against civilian targets in Kabul and other major cities, including Jalalabad, which has seen three major attacks in the past two weeks alone.

"Apparently a suicide bomber detonated his explosive vest at the gate of our ministry," said Fraidoon Azhand, a spokesman at the Ministry of Rural Rehabilitation and Development.
