The uproar over the burning of the flag of a hardline Islamist group by members of Indonesia’s largest Muslim organisation threatened to boil over as thousands of conservative Muslims demanded that those responsible be taken to task, The Jakarta Post reports. Hundreds of protesters took to the street on Friday against the recent burning of a black flag bearing an Islamic creed written in Arabic, demanding that the government and law enforcement prosecute the actors who had set the flag on fire. Three men who burned the flag during National Santri (Islamic students) Day in Garut, West Java, had already apologized for what they did. They have also been detained in police headquarters for safety reasons while waiting for the legal proceedings until the situation calms.
