One US service member was missing and three others ​were wounded but in stable condition ‌after their MH-60S Seahawk helicopter made an emergency landing in the Arabian Sea ​on Wednesday, the US military ​said, adding there was no indication ⁠the crash was caused by ​hostile action.

“US Navy assets in the ​region are currently searching for other aircrewman still missing. The cause of the incident is ​under investigation,” the US Navy’s 5th ​Fleet said in a statement, adding that ‌the helicopter was deployed to the region on the USS George H.W. Bush aircraft carrier.

Helicopter water landings can be ​dangerous, even ​for ⁠experienced pilots, given the propensity of top-heavy aircraft to flip ​upside-down during submersion.

US forces ​in ⁠the region are also on high alert amid periodic flare-ups in violence ⁠during ​the ceasefire between the ​US and Iran.
