An explosion has occurred outside the foreign affairs ministry in Afghanistan's capital Kabul, causing casualties, a police official says.
The blast hit about 4pm on Wednesday, Kabul's police spokesman Khalid Zadran told Reuters.Â
He did not provide details on the number of casualties.
The Taliban-run administration has faced an insurgency by Islamic State militants who have targeted foreigners at certain sites, including the Russian and Pakistani embassies and a hotel catering to Chinese businessmen.
The blast took place at a busy time of day in a heavily fortified area surrounded by checkpoints on a street housing several ministries.
A person in a nearby office who asked not to be named as they were not authorised to speak to media described hearing a loud explosion and said they were later removed from their building.
Some countries, including Turkey and China, also have embassies in the area.
