A suicide car bomb has exploded in the Afghan capital, Kabul, killing at least 24 people, officials have told the BBC.
At least 42 were also injured and there are fears the casualties could rise.
The blast in a mainly Shia district in the west of the city struck a bus carrying government employees from the ministry of mines.
The Taliban have said they carried out the attack. Kabul has seen a number of deadly attacks this year blamed on the Taliban or so-called Islamic State.
Security forces cordoned off the area of Monday’s blast.
A spokesman for deputy government Chief Executive Mohammad Mohaqiq suggested the attackers may have been trying to target the politician’s home but “were stopped by guards”.
