The search will continue for missing crewmembers of a cargo vessel that sank off eastern Japan, after tapping sounds were heard from inside on Monday.
The Senshomaru, with a crew of five, collided with another freighter before dawn on Sunday in waters off Chiba Prefecture near Tokyo.
The captain has been rescued. One crewmember has been confirmed dead. The remaining three are missing.
The vessel is lying on its side on the seabed about 30 meters below the surface.
The Japan Coast Guard says divers have heard tapping sounds that seem to be coming from crew quarters. Murky waters have stopped the rescuers from pinpointing the location.
The coast guard plans to deploy 18 divers for the rescue operation that will resume on Tuesday morning.
A Maritime Self-Defense Force rescue vessel is heading to the scene.
It is carrying a vehicle capable of rescuing people from a sunken ship that's under heavy water pressure.
