Original Story — At least 10 people were killed and four wounded in a bomb attack in Afghanistan's capital city of Kabul on Wednesday, TOLO News reported. It is not clear whether the blast was a suicide attack or a roadside bomb. 

The blast, aimed at a bus carrying court employees, took place in the outskirts of Kabul city. The attack in Bagh-e-Daoud area of Paghman district occurred when the officials were travelling to Wardak district. 

No group has claimed responsibility for the attack yet. 

Bomb blasts in buses carrying government employees is commonplace in the city. 

The Taliban and the Islamic State group are active in the country. The Afghan government, the U.S., Pakistan, China and Russia had tried bringing the Taliban to the table for talks over ceasing hostilities in the country. However, after the U.S. recently killed the leader of Taliban in a drone attack in Pakistan, it seems the talks fell through. 

The Afghan Taliban have announced a new leader, Mawlawi Haibatullah Akhundzada, as replacement for deceased Mullah Akhtar Mansour.
