Turbulent waters north of an Island near Australia caused a boat carrying asylum-seekers to capsize Tuesday night leaving four passengers dead, according to Australian Customs and Border Protection. Approximately 150 were on board the vessel, according to the Australian Maritime Safety Authority. A Royal Australian Air Force plane and an operation by the Australian navy rescued 144 people about 70 nautical miles off the island. The Australian Maritime Safety Authority's Rescue Coordination Centre coordinated efforts to gather passengers to safety. It was not clear whether other passengers were missing, or where they were from, according to a report of CNN.
