South Korea increases security for summit

South Korea imposed heavy security today for a summit with south-east Asian leaders following North Korean nuclear and missile tests that frayed nerves across the region.

The summit venue of Seogwipo - on the island of Jeju off the southern coast - is the furthest city away from the North. Still, a nervous South Korean government is taking no chances, positioning a surface-to-air missile outside the venue aimed towards the north.
