At least 17 people were killed in a blast that targeted a mosque in northern Afghanistan on Friday, according to local sources.

The explosion occurred at the Takiakhana Imam Zaman mosque in the city of Pol e Khomri, the capital of Baghlan province, during congregational Friday prayers, the sources said.

Most of those attending prayers were from the Shia sect.

Iranian consulate in Mazar e Sharif condemned the explosion “which led to the martyrdom and wounding of a large number of praying Muslims.”
