AUSTRALIA (CNN) - A sea search off Australia's east coast for three missing US Marines was called off early Sunday, the military said.

The three Marines have been missing since what the Marine Corps calls a "mishap" with an MV-22 aircraft on Saturday.

Twenty-three of the 26 personnel on board the aircraft were rescued, the Marine Corps said.

    US military aircraft and boats scoured ocean waters off Australia searching without success for the three missing Marines.

    The families of the missing Marines have been notified, the military said.

    "Operations have now shifted to recovery efforts," the Marines said in a news release.
