7 May 2013 Last updated at 21:46 BST

US President Barack Obama has said North Korea will no longer be rewarded for provocative behaviour at a joint appearance with South Korean President Park Geun-hye.

The leaders affirmed the security alliance between their countries, at the White House briefing.

Ms Park is making her first visit to the US since taking office in February, and held talks with Mr Obama on Tuesday.

Ahead of their meeting, US officials said North Korea had moved two medium-range missiles from a coastal launch site, lowering tensions.
