3 U.S. Marines killed in Osprey aircraft crash in Australia

At least three U.S. Marines were killed Sunday when an Osprey aircraft carrying 23 personnel crashed on a north Australian island during a training exercise, U.S. military officials said. 

Five others were transported to a local hospital in serious condition. Northern Territory Chief Minister Natasha Fyles said Sunday morning that an emergency response was underway to triage the victims and take them to local hospitals.

"Recovery efforts are ongoing," the Marines said in a statement.
