About 3,000 South Koreans, most of them Christians, have held a rally in the city of Busan to show their support for the United States, and to call for North Korea to give up its nuclear programme.

Members of the crowd waved American flags and burned a North Korean flag.

The demonstration follows a wave of anti-US protests late last year, which started after two South Korean girls were knocked down and killed by an American army vehicle.
