Following Friday's suspected suicide blast at the barracks of Rapid Action Battalion (RAB) in Dhaka's Ashkona, Road Transport Minister Quader went on record blaming the BNP for it.
His latest remarks came on Saturday after RAB said it foiled a possible suicide attack on a check-post in the capital's Khilgaon.
"Since the national elections are only a year and half away, these attacks will definitely get in the way of the polls," he said while speaking at a programme in Dhaka. "No one is safe when such attacks multiply."
The senior Awami League leader said the attacks were a part of a conspiracy to taint Bangladesh's image in the global arena.
"They are targeting RAB and police to demoralise the security forces and now they have the chosen March, the month of independence."
After security forces' crackdown on militancy following the Gulshan and Sholakia terror attacks in July last year, the militants had appeared weakened, but recent incidents suggested that they were re-grouping and a leadership was in charge.
