Indonesia stepped up security at tourist spots and embassies following the executions of Amrozi, 47, his brother Mukhlas, 48, and ringleader Imam Samudra, 38, which sparked brief clashes between police and hundreds of mourners. The three men were killed with shots to the heart shortly after midnight near their prison on Nusakambangan island off southern Java, said attorney general's office spokesman Jasman Panjaitan. They refused an offer of blindfolds and cooperated fully with their executioners, he said. "All three convicted men were very cooperative and didn't resist at all. The families have also been cooperative and sincere," Panjaitan said. A source in the prison told AFP they shouted "Allahu Akbar" (God is greater) as they were escorted out of their isolation cells shortly before midnight on Saturday. The 2002 attacks targeted packed nightspots on the holiday island of Bali, killing more than 160 foreigners including 88 Australians, as well as 38 Indonesians. Until the end, the bombers expressed no remorse for their "infidel" victims and claimed they wanted to die as "martyrs" for their dream of an Islamic caliphate spanning much of Southeast Asia. Survivors and relatives of the victims expressed a mixture of relief and sadness at the news. "I guess the overwhelming feeling isn't joy because they're dead, but it's definitely relief that we don't have to continue with the circus," said Trent Thompson, whose brother Clint was among the Australians killed.
