A boat carrying as many as 170 people believed to be asylum seekers bound for Australia has sunk off the south coast of Indonesia, with up to 60 people feared dead or missing, the Australian news media reported Wednesday. The latest disaster at sea involving boat people came less than a week after Australia slammed the door on would-be refugees with a deal to send all boat arrivals to Papua New Guinea for assessment and eventual settlement. As many as 170 people were on board the vessel, which broke up in heavy seas late on Tuesday, News Ltd. reported. More than 100 people, mostly from Iran and Sri Lanka, were rescued by fishermen in the area overnight, it said.
