"I am seeking support and cooperation of all in the movement I will continue till the criminals are punished," Asma said at a rally at the Central Shaheed Minar in the capital.

The rally was organised by Sammilita Peshajibi Parishad, a forum of professional bodies, to protest the killing of Kibria in a grenade attack in Habiganj on January 27.

Lawyers, former diplomats, women's rights activists, physicians, cultural activists, university teachers and opposition politicians also addressed the rally and expressed solidarity with her movement.

Asma declared that her peaceful movement would begin with a 30-minute silent protest tomorrow afternoon when she and her family members would take to street. They will demonstrate in front of their Dhanmondi residence from 3:00pm to 3:30pm. She urged all to participate in the demonstration.

"My lone voice is not enough ...Please come and join us in the protest programme," said a sobbing Asma, also an artist.

Nazli Kibria, daughter of the slain minister, said she would launch an international campaign against her father's killing. "I will go to the international community and expatriate Bangladeshis in different countries, and seek their support," she said.

An emotion-charged Nazli again blamed the government for negligence to treatment of her injured father. "My mother and other family members tried their best to manage a helicopter but failed," she added.

She also alleged the government has resorted to 'falsehood' about international probe into the carnage. " They (government) have not yet made any formal requests for this," she said.

The rally, chaired by Barrister Rokanuddin Mahmud, also addressed by Prof Anisuzzaman, Barrister Amir-ul-Islam, Prof AK Azad Chowdhury, Prof AAMS Arefin Siddique, Abdur Razzak MP, Mosatafa Jalal Mohiuddin, Shirin Akhter, Mamunur Rashid, Tarana Halim and Kibria's sister Sharifa Musaddit.

They stressed unity of pro-liberation and progressive forces against the ruling alliance, and said if it continues in power, such killings will not end.
