The two channels -- Diganta Television and Islamic TV -- are known to be pro-Jamaat-e-Islami.
Authorities have accused the two channels of airing "provocative commentaries" in their live Dhaka siege" programme of Hefazat-e-Islam group.
"They provoked violence spreading hatred and rumours," information minister Hasanul Haq Inu told a press conference at his secretariat office.
"The media enjoyed maximum freedom during the incumbent government but unfortunately the Diganta and another one or two TV channels showed extreme irresponsibility, committed severe crimes by provoking violence through spreading malice and rumours", he said.

The press conference came as authorities overnight stopped broadcast of the channels, after violence erupted over the Hefazat's demonstrations when they aired live the radical group's activities with their own "provocative commentaries".
The minister also blasted the radical group asking the newsmen if their activities proved they could be "custodians of Islam" and added that their 13-point demand which calls for enactment of a blasphemy law was redundant.
Inu said even if any atheist was there on an individual level in Bangladesh, "they don't have the capacity to pose slightest threats to Islam or any other religion".
