A suspected bomber died in what is believed to be a suicide blast at a camp of the Rapid Action Battalion (RAB) in Dhaka's Ashkona area on Friday.
The bomber died on the spot and two Rab men were "slightly injured," The Daily Star quoted Mufti Mahmud Khan, director of the force's legal and media wing, as saying.
The Ashkona Rab camp is a proposed site for the headquarters of the elite force. Currently, it is mostly an empty space fenced by brick walls.
Mahmud said that the man climbed over the fencing and trespassed into RAB property around 1:30 p.m.
"When challenged, a bomb he was carrying exploded," he said.
The reported attack comes only two days after the Islamic State called for suicide attacks in Bangladesh and a day after police busted a suspected militant den in Chittagong's Sitakunda.
