A US aircraft carrier arrived in South Korea Sunday for manoeuvres, a media report said, amid increasing tensions with North Korea.
The atomic-powered USS John C Stennis is visiting the port of Pusan and will take part in the Key Resolve military exercises involving US and South Korean forces, the Yonhap News Agency reported.
Three US guided-missile destroyers and a cruiser will also participate in the visit to the port on the south-east coast of South Korea, 450 kilometres from Seoul.
The USS John C Stennis weighs 103,000 tons and has a maximum speed of 56 kilometres per hour.
The Key Resolve exercises are held annually.
Tensions have risen on the Korean Peninsula since North Korea carried out its fourth atomic test in January and a long-range rocket launch in February.
