KABUL: An Afghan official says a suicide bomber struck a vehicle carrying court employees in Kabul, killing 10 people.

Najib Danish, the Interior Ministry's deputy spokesman, said the bomber, who was on foot, detonated his explosives vest as he walked by the vehicle in the Afghan capital on Wednesday.

He says the explosion, which took place during the morning rush hour in the western part of the city, also wounded four people.

The casualties include both court workers and civilians. No one has yet claimed responsibility for the attack.

The attack comes as the Afghan Taliban named a new leader following Mullah Akhtar Mansour's death in a US drone strike on Saturday. The last major attack in Kabul was on April 19, when a massive bomb killed 64 people and wounded hundreds.
