Ex-terror convict Abu Bakar Ba'asyir, known as the spiritual leader of shadowy militant group Jemaah Islamiyah that aims to establish an Islamic state in Indonesia, did the unthinkable on Wednesday as he participated in the Independence Day ceremony at his boarding school in the Central Java district of Sukoharjo. It was also the first ever August 17 ceremony to be held by the Al Mukmin Islamic Boarding School since Ba’asyir founded it in 1972.
