In a statement, the Governorship of Istanbul said the fire broke out at around 13:30 p.m. (1030 GMT) in the historical mosque along the Bosphorus in Uskudar district.

Firefighters, with the support of the Coast Guard Command, doused the blaze.

The mosque, mainly made from wood, was built by Vani Mehmet Efendi, a Turkish scholar, in 1665.
