DENPASAR - EMOTIONS ran high in Bali on Sunday as Indonesia executed three Islamists convicted for the 2002 bombings on the island which killed more than 200 people and ruined the local tourism business.

Amrozi, 47, his brother Mukhlas, 48, and ringleader Imam Samudra, 38, were executed by firing squad near their prison on Nusakambangan island off southern Java just after midnight on Sunday.

Chris Hargraves, a 45-year-old Australian who ignored his government's warning against unnecessary travel to Indonesia, said he was glad for the victims.

'I reckon it's good. It's about time for some of the other victims (who survived). It's finally finished,' he said as he paid his respects to the dead - including 88 Australians - at a monument on Kuta beach.

British tourist Mandy Carter, 25, said she was afraid the bombers' radical sympathisers could stage reprisal attacks despite a massive security clampdown around sensitive areas including Bali's famous tourist strip.

'I heard about the (Australian) travel warning. Frankly I'm a little bit scared of any retaliation from the extremists,' she said.

Ms Tumini, a survivor who worked at Paddy's bar which was torn to pieces by one of the bombs, said she was 'happy' the executions had finally been carried out after five years of appeals and legal challenges.

'I'm feeling happy. I don't have any resentment towards them. I only hope that this problem (of Islamic radicalism) can be solved at its roots,' the badly-scarred survivor told reporters at a joint prayer session.

Balinese man Adi Wiraguna, 32, said he hoped the executions would help the Hindu-majority island put the tragedy behind it.

'The Balinese people have been waiting for this. Now I just hope that Bali will really get back to normal,' he said. -- AFP
