Indonesia's Supreme Court has given three young Australians death sentences for heroin trafficking after prosecutors appealed against an earlier cut in their jail terms, a court official said on Wednesday.
A fourth Australian man was also given a death sentence after appealing against his life term, Zarof Ricar, director of criminal justice at the Supreme Court, told reporters.
The rulings are likely to strain ties between the two neighbours and Australian Foreign Minister Alexander Downer told reporters in Canberra that an appeal for clemency would be filed.
According to the court official, six of the so-called "Bali Nine" gang arrested on the resort island last year while trying to smuggle more than 8.2 kg (18 lb) of heroin into Australia now face execution.
The court handed down death sentences to Tan Duc Thanh Nguyen, Si Yi Chen and Matthew Norman, the official said. This was also confirmed by court documents seen by Reuters. The three were among five from the group to have their life sentences cut to 20 years in April after an appeal at the Bali High Court.
