Casualties in suicide attack on Kabul election workers: officials

A suicide attacker on foot blew himself up near a vehicle as it entered the head office of Afghanistan's Independent Election Commission (IEC) on Monday, wounding at least six people, officials said.

"The explosion happened 20 metres from the vehicles of the IEC employees," Kabul police spokesman Basir Mujahid told AFP.
