KURIGRAM, BANGLADESH - MARCH 23: The wife, mother and children (L-R Nasima Akhter, Rahul Amin Azad, Esimon Begum, Ambia Begum, Hasina Begum) of Christian convert Hossain Ali, who was murdered by ISIS, hold his photograph as they pose for a photo March 23, 2016 in Kurigram, Bangladesh. On March 22 Ali was taking his usual morning walk when he was attacked and died. Ali was a Navy Commander during Bangladesh's 1971 Liberation War, and converted to Christianity 16 years ago. The police warned him and his family to be careful and limit their movement because of the ongoing security issues, but Ali felt safe since he said he had no enemies. ISIS claimed responsibility for his murder. He is remembered as a gentle, simple and happy man, and he leaves behind a wife, mother, and three children. Amid the attacks in Brussels on Tuesday, ISIS also claimed responsibility for stabbing Hossain Ali, a Christian convert, to death in northern Bangladesh on the same day, the latest killing declared by the militant group in the Muslim-majority nation. The country has seen a surge in Islamist violence where liberal activists, minority Muslim sects, foreigners and other religious groups have been targeted. The terrorist networks are popping up all over the world and in recent months, Bangladesh has seen a series of attacks on bloggers, foreigners, and religious groups including Shiite, Ahmadi Muslims, Christians and Hindus. Since 2013, six bloggers have been murdered with others also attacked, and since September 2015 ISIS has claimed responsibility for twelve attacks throughout the Muslim majority country.
