Outrage over Aung San Suu Kyi's house arrest will not detract from relief work, key donors said, as the United Nations on Wednesday reported small gains in getting aid to cyclone survivors.

The military regime quietly informed the Nobel Peace Prize winner that she would spend another year confined to her home in Yangon, where she has been locked away for most of the last 18 years.

The decision came just two days after UN Secretary General Ban Ki-moon left Myanmar following a donor conference that generated tens of millions of dollars in aid pledges in response to the cyclone that left 133,000 dead or missing.
