At least five people died including four doctors after a magnetic bomb attached to their car exploded in the Afghanistan capital, Kabul.
The doctors were heading to the Pul-e-Charkhi prison, located on the eastern outskirts of Kabul, which hosts hundreds of Taliban fighters, according to Kabul police.
It was not immediately clear if the doctors were targeted in Tuesday’s attack.
The fifth person killed in the explosion is yet to be identified.
Two others were injured in the explosion, said Faramarz.
No one immediately claimed responsibility for the attack which damaged nearby buildings and shops.
The ISIL (ISIS) group is said to be behind multiple attacks in Kabul in recent months.
ISIL also claimed responsibility for Saturday’s rocket attacks at a United States military base in Afghanistan.
On Monday, gunmen murdered Afghan journalist Rahmatullah Nekzad in the eastern city of Ghazni.
The previous day, a car bomb explosion in Kabul killed at least nine people and wounded more than 15.
Violence involving the Taliban has also continued despite peace talks between the group and Afghan officials in Doha, Qatar.
The negotiations, which have seen some progress on preliminary issues, have been paused until January.
The two sides are yet to begin discussing a ceasefire or power-sharing arrangement.
Last month the US announced plans to withdraw 2,000 troops from the country by mid-January.
