LAHORE (Agencies) - The minister for minority affairs on Thursday called for a thorough re-investigation and fair appeal for a Christian mother sentenced to death for blasphemy after the Pope called for her release. On November 8, Asia Bibi was sentenced to hang in Punjab after being accused of blasphemy against Holy Prophet Muhammad (PBUH) in 2009. She has filed an appeal at Lahore High Court. We have requested the Punjab government that the trial should be fair in the high court. She must also be provided security in jail, said minister for minority affairs, Shahbaz Bhatti. Asias supporters say the case is baseless and that her first trial was not heard properly, Bhatti told AFP. We have, therefore, asked the Punjab government that the case be reinvestigated properly. Pope Benedict XVI this week called for her release and said Christians in Pakistan were often victims of violence and discrimination. The pontiff said the mother of five should be given back her freedom, during the weekly general address in St Peters Square, a Vatican statement said. I feel close to Asia Bibi and her family and I ask that she be released as soon as possible, he said on Wednesday. I pray for those who find themselves in similar situations so that their human dignity and fundamental rights are respected, Benedict said. Italys Foreign Minister Franco Frattini said he was told during a visit to Islamabad last week that Pakistan was committed to changing the blasphemy law and has promised to join the fight to save Asia. Asias lawyer said the appeal had been filed. Neither he nor her husband, Ashiq Masih, said there had been any contact from the government. The Lahore High Court will take up the case. It can order a fresh inquiry, a fresh trial or a fresh investigation, lawyer SK Chaudhry told AFP. We will move a bail application for Asia next week and we hope the court will grant her bail, Chaudhry said. Meanwhile, an international human rights advocate has joined calls for the release of the Christian woman. Amnesty International on Friday also called on Pakistan to revise the law under which mother of five Asia Bibi was convicted this month.
