The blast hit around 4 p.m. local time (1130 GMT), police spokesman Khalid Zadran added.

The Taliban-run administration has faced an insurgency by Islamic State militants who have targeted key installations including the Russian and Pakistani embassies and the office of the former prime minister in recent months.

Spokespeople for the Taliban-run foreign affairs and interior ministries did not immediately respond to requests for comment on Wednesday.
