A DEFIANT President Suharto left his troubled Indonesia for the first time in six months as protests continued and a key political ally pledged a time limit on any new leader's rule. Before leaving for Egypt for a summit of developing nations, Mr Suharto said he was not against reform but warned that his feared security forces would not tolerate threats to national security. 'I hope the people of Indonesia will not sacrifice the national stability that we have achieved,' he said. 'The security forces will take action against whoever disturbs and ruins national stability.' Protests involving students and civil servants intensified in the central Java city of Yogyakarta after word spread of the death of Mozes Gatotkaca, a 40-year-old businessman, after a beating from security forces on Friday. Some reports said he was a bystander, others said he was a part-time student. Army and police units were also prominent across the capital Jakarta and in Medan, on Sumatra, where six people died in rioting on Wednesday in the worst violence since protests against Mr Suharto's 32-year rule intensified in February. The chairman of Mr Suharto's ruling Golkar party pledged that plans to limit the presidency to two terms would be on the agenda for future political reforms. In a bid to ease widening tensions, Mr Harmoko said the party would push for the measures to take effect after Mr Suharto's seventh five-year term ended in 2003 - a term he said Mr Suharto deserved due to his 'unique qualities'. 'My conclusion is as the chairman of Golkar, Pak Harto [Suharto] does not want and will not run again,' he said. But the 76-year-old leader had no intention of standing down, he said. In the latest sign of widening international concerns at the crisis, the Pentagon has shelved a routine joint-military exercise with Indonesia. 'We thought it would be inappropriate to continue training at this time,' a spokesman said.
