State Minister for Liberation War Affairs Ishraque Hossain resigned on Monday, telling a press conference at the National Press Club that he had asked Prime Minister Tarique Rahman to relieve him so he could focus on an anti-drug campaign in Dhaka-6 and nearby areas.

"I told the prime minister that I want to resign because I believe this anti-drug campaign has only just begun and must continue," he said, adding that he did not want the row to overshadow the government's work or embarrass the BNP.

The announcement followed a night of confusion. Several outlets reported on Sunday that the prime minister had ordered him to resign, and Ishraque called the report false. On Monday morning he said he would announce his resignation at a press conference, and by the afternoon he had done so.

The row began on Saturday, when video posted on his own Facebook page showed him carrying a pistol during a drive near the Ghuntighar railway crossing in Gendaria. Six people were detained and handed over to police, he said. The Dhaka Metropolitan Police said its Wari zone deputy commissioner was investigating whether any law had been broken.

Ishraque defended the operation, saying Ghuntighar and Munshitek had become drug hubs, that police were told in advance, and that he carried a licensed weapon briefly for his own safety. He apologised to anyone who might have been hurt and said he had done nothing wrong.

He said he would keep the campaign going as a BNP activist and that the prime minister had agreed to let him continue. He also criticised media coverage, saying it had shifted the focus from the drug trade to his firearm.
