Geneva, Sep 27 (DPA) The Lebanese population faces a "ticking timebomb" from the 100,000 unexploded bombs estimated to be littering the towns and countryside, UNICEF warned Tuesday.

Fourteen people were killed, two of them children and 90 injured after triggering the bombs since the end of Israel's recent 33-day conflict with the Lebanon-based Hezbollah movement, said the UN children's agency.

"This is now the biggest threat to lives," said UNICEF spokesman Michael Bociurkiw. "It is literally a ticking timebomb for the children of Lebanon, all of whom have already suffered too much from the conflict."

The UN has identified 400 strike sites where hundreds of thousands of bombs fell with an explosion failure rate of 10-40 percent.

Cluster bombs were the most dangerous as they could be triggered by vibrations and were often found hanging from trees or houses.

"They are more likely to cause death than injury making them more lethal than landmines," he added.

A few days ago a young boy climbing a tree was killed when a cluster bomb hanging from the branches fell onto his head and exploded.

The danger was very real during the current harvest when villagers, including children, would be helping farmers gather crops, Bociurkiw said.
