South Korea probes computer 'attack'
South Korean officials are investigating a suspected cyber-attack that has paralysed computer networks at broadcasters and banks.
The cause of the problems remains unknown but appears to have been caused by a virus, an official close to the investigation told the BBC.
Last week, North Korea accused the US and its allies of attacks on its internet servers.
Tension has been high on the Korean peninsula following Pyongyang's nuclear test in February.
