Dhaka, Jan 25 (ANI): Hundreds of working professionals gathered in Dhaka to protest against alleged "militant activities" by political activists during a countrywide strike and blockade called by opposition, Bangladesh Nationalist Party (BNP). People in large numbers gathered with banners and placards showing photographs of a burnt bus and injured victims as a mark of protest. Chief of BNP and former Prime Minister, Begum Khaleda Zia, whose party boycotted the election on January 05 last year, has demanded that Sheikh Hasina and her government step down for a new vote under a caretaker administration. Veteran film artist, Syed Hasan Imam, demanded justice for victims of such political activities. Hasina and Khaleda have alternated as prime minister for most of the past two decades in a fierce rivalry marked by periods of widespread political violence.
