Maersk Line, has suspended service to three tsunami-hit Japanese ports, it said.

Maersk Line, a unit of Danish shipping and oil group A.P. Moller-Maersk, said in a weekly news bulletin that it suspended service to Sendai, Onahama and Hachinohe.

"We have limited details at this moment, but terminal facilities and our containers at these ports have suffered serious damages by the tsunami," Maersk said.

"Tokyo, Yokohama, Nagoya, Kobe, Osaka and Hakata ports are safe and no damages have been reported to our equipment in these yards," it said.

Maersk Line continues to serve other Japanese ports as usual for now, but service may be subject to changes later, it said. (Reuters)
