A suicide bomber has killed 20 people at a police headquarters in the Afghan capital Kabul, officials say.
At least 29 others were wounded in the blast in the west of the city, the interior ministry said.
Some reports suggest most of those killed and injured were police officers. Earlier reports said most of the dead were civilians.
The Taliban said they carried out the bombing - one of a string of attacks in Kabul and elsewhere in recent months.
Monday’s attack happened at the entrance of the headquarters of the National Civil Order Police, a unit that has a counterinsurgency role against the Taliban.
