Washington:
Search and rescue operations were underway after a US Navy helicopter crashed into the sea off the coast of California, the US Pacific Fleet said on Tuesday.
The MH-60S helicopter took off from the USS Abraham Lincoln during "routine flight operations" about 60 nautical miles off the coast of San Diego at 4:30 pm (2330 GMT), the fleet said on Twitter.
"Search and rescue operations are ongoing with multiple Coast Guard and Navy air and surface assets", the post said.
It was not immediately clear how many people were on board.
