The intelligence chief of Bangladesh's anti-crime elite force -- Rapid Action Battalion (RAB) died from blast injuries Friday at the Combined Military Hospital (CMH).
An official said, "RAB Intelligence Wing Director Abul Kalam Azad died at CMH at around 12:05 a.m. (local time) on Friday."
Azad, hit by splinters in the March 25 blast in Sylhet, was flown back to Dhaka Wednesday night on life support from a Singapore hospital where he had been taken on Sunday for better treatment.
With Azad, death toll in the twin blasts near a militant den in Sylhet has risen to seven, including two police officials and four civilians. Dozens of people were injured in the blasts.
The Islamic State (IS) has reportedly claimed responsibility for the blasts.
Four militants were killed in an assault on the militant hideout, led by commandos of Bangladesh Army Para-Commando Battalion.
Brigadier General Fakhrul Ahsan, a spokesperson of the operation, said at a press briefing on Monday night that they found four bodies inside the militants' hideout.
