Cargo ship vanishes on way to China
It was due to arrive on Thursday but the last radio contact was on Sunday.
A rescue ship is being sent to the last known location of the vessel.
Rescue coordinator Leonid Ivanichev told Russia Today a Japanese plane had failed to locate the ship.
“We asked our colleagues at Chinese and Japanese rescue centres for help. Japanese rescuers immediately sent a plane to the vessel’s last known location. It searched the area but failed to locate the vessel,” Ivanichev said.
