LAHORE - Religio-political leaders, families of those killed in bomb blasts detonated or caused to detonate by Sarabjeet Singh and relatives of the Pakistanis languishing in Indian jails on Thursday called for no leniency towards the Indian terrorist. He should be hanged without delay, cried one relative of a victim while expressing her sentiments at a seminar held at the Hameed Nizami Hall, which was packed to capacity. Strongly opposing the mercy pleas made by various circles, they said even President Zardari had no Islamic or moral authority to set free such a person who had killed a large number of innocent people. Defence of Pakistan Forum Convener Ameer Hamza, Jamaat-i-Islami deputy secretary general Dr Fareed paracha, Tanzeem-i-Islami Information Secretary Muhammad Ayub Mirza, Jamaatud Dawa Lahore chief Muhammad Shahid, Civil Society Forum President Ishaq Mayo were among the speakers. Relatives of those killed in the blasts raised slogans against the Indian terrorist and sought his execution. Critical of the so-called human rights organizations seeking clemency for the terrorist, the speakers said they should also have taken in mind the sentiments of the families whose loved ones had lost their lives in blasts organized by the Indian terrorist. They said while the family members of Sarabjeet Singh were meeting with the condemned prisoner, Pakistanis in Indian jails had not been extended a similar facility. They made it clear that in case President Zardari 'misused his powers to save the life of a terrorist and a condemned prisoner, he would be betraying the PPP and the late Benazir Bhutto. Sister meets terrorist: Dalbir Kaur, the sister of Sarabjeet Singh, an Indian terrorist on death row in Kotlakhpat Jail for executing multiple bomb blasts in Lahore and Faisalabad in 1990s, on Thursday met him in the prison cell under tight security. She was granted permission by the Lahore High Court to meet him in Kot Lakhpat jail a day earlier. Awais Sheikh, the lawyer of Sarabjeet Singh also accompanied her on this occasion. Sarabjit Singh is facing death sentence after he was convicted of carrying out four bomb blasts that killed more than 14 innocent people in Lahore and Faisalabad.
