Lebanon's state-run National News Agency says a cluster bomb left behind by Israeli forces has wounded six boys, one of them seriously.

NNA gave no further details about Friday's explosion on the outskirts of the southern village of Zibqine, close to the Israeli border.

Local TV stations aired footage of the boys being treated at a hospital.

According to the U.N. mine center, more than 30 Lebanese civilians have died in cluster bomb or land mine blasts in Lebanon since the 2006 war between Israel and the Hezbollah militant group.

The United Nations and human rights groups say Israel dropped about 4 million cluster bomblets during the 34-day conflict. U.N. experts say that up to 1 million of these devices failed to explode and endanger civilians in the area.
