"Huge numbers" of people went back to their homes in southern Lebanon at the weekend, after a ten-day ceasefire came into effect on Friday, and just found "rubble", the UN humanitarian chief tells the BBC.

"Five of the six bridges that we use to get our goods across have been destroyed now so that makes it even more complicated for us to get help in but also for civilians to get back [home]," Tom Fletcher adds on Radio 4's Today programme.

He says the UN was able to deliver a couple convoys of food, medicine and blankets over the weekend.

For weeks, Israeli forces have been hitting bridges over the Litani River which link southern Lebanon to the rest of the country, saying it is targeting Hezbollah forces and their operations.

As part of the ceasefire, Lebanon must take "meaningful steps" to prevent Hezbollah and all other "rogue non-state armed groups" from carrying out attacks against Israeli targets. Israel said this morning it had hit a Hezbollah rocket launcher in southern Lebanon.
