Frustrated rescue workers will have to wait until Saturday to make a third attempt to free a humpback dolphin and her calf from a small Thailand lagoon where the Asian tsunami dumped them 10 days ago, a wildlife expert said today.

Forensic experts have begun exhuming 300 tsunami victims in Thailand after discovering their bodies apparently were mislabelled in the rush to bury the dead, officials said today. All of the bodies affected by the problem were Asian.

Teams of forensic experts packed bodies in dry ice today as Thailand’s government announced that its death toll in the tsunami disaster had doubled to more than 4,500 people – almost half of them foreigners – and hopes faded that more survivors would be found.
