Kathmandu, May 13 (RHC)-- The U.S. military says one of its warplanes has crashed shortly after taking off from an aircraft carrier in the Persian Gulf, while one Marine helicopter has gone missing in Nepal.

The F/A-18F Super Hornet fighter jet took off from the USS Theodore Roosevelt and crashed shortly afterwards. The U.S. Navy did not immediately offer the reason for the crash, but suggested it was an accident. The Navy says it is investigating the cause of the crash.

The two personnel from fighter jet ejected and were quickly recovered by search and rescue personnel from the carrier, the statement said. The aircraft carrier was in the Northern Persian Gulf, to support the U.S.-led airstrikes against the ISIL Takfiris wreaking havoc in Syria and Iraq.

Meanwhile, the U.S. military said one its Marine helicopters went missing on Tuesday near Nepal's Charikot. The UH-1Y Huey with two Nepalese soldiers and six U.S. Marines on board disappeared over Charikot, Nepal, according to U.S. Pacific Command spokesman Army Maj. Dave Eastburn.
