Israel's defence minister has said a buffer zone will be set up inside southern Lebanon and that Israel will keep security control over a swathe of the territory even after the end of the current war against the armed group Hezbollah.

Israel Katz said the area to be occupied would go up to the Litani River in southern Lebanon - about 30km (18.6 miles) from the border with Israel.

He also said all houses in Lebanese villages near the Israeli border would be demolished.

Israel sent ground troops into southern Lebanon on 2 March and has also been launching broad strikes across the country.

The action was taken after Hezbollah fired rockets into northern Israel in retaliation for Israel's assassination of Iran's supreme leader in late February, at the start of the war with Iran.
