Bahrain hunger striker's life in danger, daughter says A Bahraini girl wears a top decorated with an image of Abdulhadi al-Khawaja at an anti-government rally on February 22, 2012. The daughter of hunger striker Abdulhadi al-Khawaja says his life is at stake He has been on hunger strike for nearly 8 weeks and may drop into a coma, she says Al-Khawaja is being moved to another prison with better medical facilities, she says He and 7 others were found guilty of a plot to overthrow royal family (CNN) -- Fears are growing that a leading human rights activist who entered the 55th day of a hunger strike in Bahrain on Tuesday may not survive the ordeal, his daughter says. Abdulhadi al-Khawaja, who was arrested last year for his role in anti-government demonstrations, has been on hunger strike for nearly eight weeks in protest at his life prison term. His daughter, Maryam al-Khawaja, told CNN he "is entering a critical phase where his life is at stake." She said her father had two doctors accompanying him at all times Monday night and was being moved to a different prison Tuesday which has the necessary medical equipment. The move is due to fears that he may go into a coma at any time, as his blood sugar and blood pressure have both further dropped, she said. One of Bahrain's most prominent rights activists, Abdulhadi al-Khawaja was arrested in April of last year for his role in the anti-government demonstrations that swept through his country in February and March. In June, al-Khawaja and seven other Shiite opposition activists were found guilty of plotting to overthrow the country's Sunni royal family. They were sentenced to life in prison. The Bahrain Center for Human Rights, a nonprofit human rights group started by Abdulhadi al-Khawaja and for which his daughter works, has appealed for his immediate release on humanitarian grounds. His life is now in serious danger, Maryam al-Khawaja said, "and getting to a situation where there might be an unrepairable damage to his physical well-being, if he survives." Maryam al-Khawaja said 13 prominent leaders had their case taken to the Court of Cassation Monday, where lawyers requested that they be released pending a court decision. The judge refused the request, and announced that the decision will be read on April 23, she said. "We urge the government to take into consideration the deteriorating health condition of Abdulhadi Al-Khawaja that cannot wait until the court's decision," she said. Any damage to the health of Abdulhadi Al-Khawaja is the responsibility of the Bahraini government, including keeping him alive. The government in Bahrain has not yet responded to requests for comment. Rights group Amnesty International also called Friday for al-Khawaja's immediate and unconditional release. Phillip Luther, its Middle East and North Africa director, said in a statement: "The Bahraini authorities have made pledges that they would release people who were imprisoned for exercising their right to freedom of expression, but the continued imprisonment of Abdulhadi al-Khawaja demonstrates that they are not serious about fulfilling such promises." The rights group considers al-Khawaja a "prisoner of conscience, detained solely for exercising his right to freedom of expression," and says he began his hunger strike in February to protest his sentence. Last week, the United Nations issued a statement expressing concern about "the health of human rights defenders who are on hunger strike in protest against their imprisonment for participating in last year's mass demonstrations." The state-run Bahrain News Agency published a statement Tuesday from the Ministry of Human Rights and Social Development in response to a critical report by another rights group, Human Rights Watch (HRW), which said Bahrain had not lived up to its commitments on reform. The ministry dismissed the criticism as rash, saying the HRW report "had ignored the positive developments in the country and the continuation of the reform process," and that it was committed to the protection of human rights.
