The grand mosque, located inside an Islamic centre complex, was undergoing renovation.
“We have discussed the possibility of continuing the renovation… the most important (thing) is we can use it (the mosque) again soon,” Jakarta’s acting governor Heru Budi Hartono told Metro TV Thursday.
The cause of the fire, which took hours to extinguish, is under investigation but police said they suspect it started from the sparks created when workers tried to cut waterproofing membranes for the dome.
Four construction workers have been questioned in connection with the fire, police added.
