At least 20 people have been killed in a suicide bombing at the Afghan Supreme Court in Kabul, officials say.
Another 45 people were injured. The number of casualties is expected to rise.
The bomber targeted the car park of the court compound, reports say. The injured are being ferried to hospitals.
There was no immediate claim for the attack, which follows a number of deadly bombings by the Taliban and other militants in recent months.
The suicide bomber appeared to be targeting employees as they left the court to go home, officials said.
In the past, Afghan courts have been targeted by Taliban militants.
The UN says civilian casualties in Afghanistan have hit a new high, with 3,498 civilians killed in 2016.
The so-called Islamic State has carried out many recent attacks in Kabul, though the militant group has mostly targeted the country’s Shia community.
