Al-Jazeera Video: UN helps free Gaza of Israeli bombs

"More than a year after Israel's military offensive in Gaza, many Palestinians in the territory are still being killed or injured by unexploded bombs and mortars left behind.

A UN bomb disposal team is now working to help clear the region of the danger.

The team's leader says they have found traces of white phosphorous - a highly toxic chemical compound - in some of the explosives.
