Khasru accused the current government of stripping away people's voting rights, human rights, right to live, press freedom and freedom of speech.
"The regime is trying to weaken the party [BNP] by jailing its leaders and workers under false charges using judiciary."
Referring to the lack of credibility of the judiciary on the global stage, Khasru said, "International community has no faith in the judiciary."
