New Delhi, Aug 6 - Mohammed Hanif Sayed, his wife Fahimida and their associate Ashrat Shafique Ansari who were sentenced to death by a special court Thursday for the 2003 Mumbai twin blasts will join a list of over 300 people on death row in Indian prisons.

The three were held guilty of carrying out the Aug 25, 2003, blasts in Gateway of India and Zaveri Bazar in which 54 people were killed and 244 injured.

According to a 2007 report released by human rights groups Amnesty International and the People's Union of Civil Liberties, at least 140 of those in death row were sentenced between 2006 and 2007. Last year, 70 people across the country were sentenced to death in India.

The report, Lethal Lottery: The Death Penalty in India, is the first comprehensive analysis of around 700 Supreme Court judgements on death penalty cases over more than 50 years and exposes a judicial system that has failed to meet international laws and standards relating to the death penalty.

According to the home ministry, there are at least 28 prisoners at the final stage of seeking presidential pardon while the rest are awaiting results of appeals to courts.

Among those whose mercy petitions are still with the president are parliament attack convict Afzal Guru, who is currently lodged in the capital's high-security Tihar jail.

While Afzal Guru is the most publicised case on the list, there are other high-profile convicts as well.
