JAKARTA -- United Nations Secretary General Kofi Annan arrived in Indonesia Friday en route to East Timor where he will be a guest of honor at Sunday night's Independence proclamation. Annan was due to hold talks later in the day with President Megawati Sukarnoputri before a joint press conference. On Saturday he is scheduled to hold a breakfast meeting with Foreign Minister Hassan Wirayuda before departing for East Timor. On Sunday evening he hands over authority to East Timor's Parliament speaker and lowers the UN flag after a unique 32-month exercise in nation-building by the world body, AFP reported. The speaker will declare independence on the stroke of midnight (1500 GMT Sunday). The Security Council was to meet in New York later Friday to set up a successor UN mission with an initial strength of 5,000 troops, 1,250 police officers and about 100 civilians to protect and support the independent nation for two years. Indonesia invaded the former Portuguese colony in 1975 and annexed it the following year in a move never recognized by the United Nations. It consented to a UN-organized ballot in August 1999 in which almost 80 percent of East Timorese voted for independence. The vote sparked an orgy of violence and destruction by pro-Jakarta militias and some elements of the Indonesian army. The UN took over government of the territory in October 1999. Annan, who last visited Indonesia in 2000, has said Jakarta should be given a chance to punish those responsible for violence in East Timor. But he has said the Security Council might decide to sanction its own inquiry if the Indonesian response is unsatisfactory. Indonesia has set up a human rights court to try 18 people accused of involvement in the violence in a bid to deflect pressure for a UN tribunal, but human rights groups have slammed the court procedures as ineffective. Human rights watch, in a statement Friday, said there is "Widespread skepticism that trials underway in Jakarta before Indonesian ad hoc tribunals will bring accountability. "Top generals implicated in the 1999 campaign have not even been indicted," it said in a statement. The New York-based group called on the UN and donor governments to increase pressure on Indonesia either to effectively prosecute all those responsible, "or turn them over to bodies that will, beginning with those already indicted in Dili." Jakarta is refusing to extradite suspects to face trial at a special court in the East Timorese capital.
