BNP Secretary General Mirza Fakhrul Islam Alamgir on Wednesday voiced concern that Dhaka has become an 'explosion-prone’ and 'dangerous' city due to the government’s extreme negligence and mismanagement.” “Explosions have been taking place one after another in the country for the past few days.  These incidents are happening as there is no supervision of the construction work of the buildings or their maintenance,” he said.

As a result, he said, there is no security in the buildings to prevent explosions and there is no system to prevent fire there. “So, such terrible explosions are happening, leaving many people dead and injured. In fact, Dhaka has now become an explosion-prone and most dangerous city,” Fakhrul said.
