Candles lit for condemned man

Human rights activists are leaving candles at the front gate of Singapore's Changi Prison, as the execution of Australian man Van Nguyen draws nearer.

They say they hope his death will not be in vain.

The execution of the 25-year-old Melbourne man is scheduled to take place in the next hour.

He was sentenced to death after being convicted of trying to smuggle nearly 400 grams of heroin through Changi Airport.

It is not expected there will be any official announcement that the execution has taken place, just the understanding that by the time the sun comes up, he will have been hanged.

One of Nguyen's lawyers says Nguyen's mother, Kim, now appears to be accepting her son's fate

Julian MacMahon says the mood among the Australians in Singapore is mixed.

"Everyone is grief-stricken in some way," he said.

"But I think pretty much everyone has come to a point of acceptance of what is the reality and thank goodness Kim has come to that point.

"I spent a lot of time with her yesterday and she's better now than she has been for months."
