Commerce minister Faruq Khan says JMB militants had links to the Feb 25-26 BDR massacre that left at least 59 army officers killed.
"Not all BDR men were involved (in the mutiny) ... and some JMB links have been found," he told reporters Thursday, emerging from a conference he launched and addressed.
Faruq, a former lieutenant colonel, was named Wednesday as head of a committee coordinating various inquiries into the carnage.
The minister told the conference audience that the BDR headquarters incident was a "deep-rooted conspiracy".
"It's a conspiracy against Bangladesh, its people and its moving forward."
Faruq came down hard on the opposition. "They have not behaved in the manner which they should have in the time of 'national crisis'."
"It was the fourth day when everything was over, they (opposition party) came up with their expert opinions," he said.
It was an AGM of International Business Forum of Bangladesh (IBFB), held at Sheraton Hotel, which also heard from state minister for foreign affairs Hasan Mahmud, USAID official Todd Sorenson and IBFB president Mahmudul Islam Chowdhury.
