SINGAPORE (Reuters) - A U.S. warship damaged after colliding with a merchant vessel east of Singapore on Monday is sailing under its own power and heading to port, the U.S. Navy said.

“Search and rescue efforts are underway in coordination with local authorities,” the Navy said in a statement posted on the website of the Commander of the U.S. Pacific Fleet.

“In addition to tug boats out of Singapore, the Republic of Singapore Navy ship RSS Gallant, RSN helicopters and Police Coast Guard vessel Basking Shark are currently in the area to render assistance,” it said.

The statement said MV-22 Ospreys and SH-60S Sea Hawks from USS America were also responding.
