YANGON8 (AFP) - Myanmar's ruling junta has extended the house arrest of Aung San Suu Kyi by another year, an official said Tuesday, as 16 of the democracy leader's supporters were arrested. Seven Myanmar officials went to the lakeside Yangon home that has been Aung San Suu Kyi's prison for most of the last 18 years and delivered the news on Tuesday afternoon during a 10-minute meeting, a state official said. "Her detention was extended by one year," the official told AFP. The Nobel Peace Prize winner's most recent period in detention began on May 30, 2003, when her convoy was ambushed while she toured upcountry. About 100 uniformed and plainclothes police, along with pro-junta militia, patrolled around the rambling lakeside house in Yangon ahead of the afternoon meeting. Earlier Tuesday, about 30 of her supporters tried to march towards her home, but security forces broke up the protest and arrested 16 people including a 12-year-old boy, a spokesman from her National League for Democracy party said. Six police trucks were stationed near the NLD's rundown headquarters in the centre of the country's main city Yangon, while plainclothes police stood watch from across the street, witnesses said. US President George W Bush led global outrage at the Myanmar ruling junta's decision to keep democracy icon under house arrest for another year. "I am deeply troubled by the Burmese regime's extension of National League for Democracy (NLD) General Secretary and Nobel Peace Prize winner Aung San Suu Kyi's house arrest," Bush said in a statement. The EU's special envoy for Myanmar, Piero Fassino, slammed the decision by the country's ruling junta as "unacceptable." The move "has no justification," the Italian Fassino said in a statement issued in Rome. Britain lamented the decision, saying it was a further indictment of the reclusive country's ruling junta. "I was saddened, if not surprised, to learn that the Burmese government has, once again, decided to extend the house arrest of Suu Kyi," Foreign Secretary David Miliband said. UN chief Ban Ki-moon voiced regret over the decision by Myanmar's ruling junta to extend Suu Kyi's house arrest. Singapore expressed disappointment over the extension of Suu Kyi's house arrest but said it should not hinder relief work for cyclone victims in the country. "We are disappointed to learn that Daw Aung San Suu Kyi's detention under house arrest has been extended by the Myanmar Govt," said a statement from the foreign ministry of Singapore.
