UN chief Ban Ki-moon has joined an international outcry as Myanmar rulers extended the house arrest of democracy icon Aung San Suu Kyi, vowing to work to get her and other political detainees released. "I regret the decision of the government of Myanmar to extend for a sixth consecutive year the detention under house arrest of Aung San Suu Kyi," the UN secretary general told reporters on his return from a visit to cyclone-hit Myanmar. "The sooner restrictions on Aung San Suu Kyi and other political figures are lifted, the sooner Myanmar will be able to move toward inclusive national reconciliation, restoration of democracy and full respect for human rights," he added.
