Indonesia's confirmed death toll from the bird flu virus rose to 14, while three patients suspected of carrying the virus were being treated in hospital, health officials said.
Two siblings from Indonesia's West Java died last week and tests by a World Health Organisation (WHO)-accredited laboratory showed they were infected with the H5N1 strain, health ministry official Hariyadi Wibisono said.
"The results from Hong Kong arrived earlier today (Saturday) and confirmed that the two had died of bird flu," he told AFP.
Wibisono said the pair, aged four and 13, were residents of Indramayu -- site of the fifth cluster case in Indonesia, the world's fourth most populous nation -- and were in contact with dead chickens near their home.
