Tons of unexploded explosives, dropped on the Gaza Strip during the three-week-long Israeli onslaught, continue to claim Palestinian lives.

On Sunday, two teenagers, aged 14 and 15, died in Gaza City, after coming across an unexploded device, a Press TV correspondent reported quoting Gazan medical sources.

The incident in the city's Zeitun neighborhood also severely wounded another teenager, who is receiving treatment in the area's Al-Shifa hospital.

Expert teams have so far unearthed seven tons of explosives from different parts of the coastal area dropped by Israeli aircraft during Tel Aviv's 'all-out' attacks, codenamed Operation Cast Lead.

The assaults, which ended on January 15, killed 1,330 Palestinians and wounded 5,450 others -- a large number of whom were women and children.

The remaining explosives are expertly camouflaged and come in all shapes. Out of curiosity, children often touch the unidentified objects which the locals and operative NGO's have been strongly advised to avoid.
