Israeli Lebanon raid worries UN

The head of the United Nations, Kofi Annan, has said he is worried by an Israeli raid into Lebanon on Saturday.

Mr Annan said he thinks the raid breaks a ceasefire organised by the UN, which brought fighting between Israel and the armed group Hezbollah to an end.

Lebanon has said it may not now do things it has promised as part of the ceasefire agreement.

Israel says it launched the attack to stop Hezbollah getting weapons from nearby countries Syria and Iran.

Part of the ceasefire agreement also bans Hezbollah from trying to get hold of new weapons.

The agreement to end the fighting in Israel and Lebanon started on Monday, and this is the most serious incident since it began.

Hezbollah is armed group in Lebanon that is also represented in the country's government. Many of its members and bases are in the south of Lebanon, which is the area nearest to Israel.

The UN ceasefire - as part of a resolution called 1701 - will see as many as 15,000 soldiers making up a force to try and keep the peace working in southern Lebanon.
