A leading rights group says that Syrian government forces have started using a more powerful type of cluster munitions rocket. Cluster bombs have been banned in many countries because they are indiscriminate and leave unexploded ordnance that can be a danger, long after the original attack. Sebastian Usher reports.

The New York based Human Rights Watch says it has been given photos of an attack on the town of Keferzita last week that showed traces of cluster munitions that contained more than 70 bomblets. It says this is much more powerful than similar weapons that Syrian forces have so far used. The town which is near the central city of Hama has repeatedly come under attack since rebels took control of it more than a year ago. It's been subjected to air strikes and shelling as well as for crudely made barrel bombs that has become a key weapon in the government's armory.
