Health officials in Turkey say tests confirm that a 12-year-old girl who died Sunday was infected with the lethal strain of bird flu.

Officials say four children in Turkey have died from the H5N1 strain, and 16 other people are infected.

In Indonesia, officials say a 13-year-old girl has died of bird flu, but tests have not confirmed if she had the H5N1 strain that has killed 12 people there.

Meanwhile, Israeli doctors are testing a man from East Jerusalem who could be their first case of bird flu.

Concerns over new infections come as the World Bank seeks more than $1 billion in donations at a global conference on fighting bird flu.

The conference, opening in Beijing on Tuesday, aims to halt the spread of the virus in developing countries and improve care for H5N1 victims.
