Information Minister Hasanul Haq Inu alleged that BNP founder General Ziaur Rahman was the mastermind of the murders of Bangabandhu Sheikh Mujibur Rahman and four national leaders.
He said: "Zia was the mastermind of the brutal murders and later he gave shelter to all the killers and conspirators behind the criminal acts."
He made the remarks while exchanging views with party leaders and activities at Kushtia Circuit House on Friday.
Noting that the BNP remains silent about the jail killing issue, he said: "After Zia, his wife Khaleda Zia takes up his role and her party is now the protecting the killers of the national leaders."
"Their [BNP leaders] silence over the issue proves that Begum Zia and her party members are directly supporting political murders and autocracy," he added.
