At least four Palestinians have lost their lives when�an explosive device left from Israel�s war�on the Gaza Strip last year, went�off in the south of the besieged enclave.

According to reports on Thursday, the explosion took place when the victims, all members of a family, were removing rubble�from a destroyed house in a refugee camp in Gaza.

Palestinian medical sources at the Abu Yousif al-Najjar hospital in Rafah stated that over 30 people were also injured in the incident.

Similar incidents have left several Palestinians dead or wounded following the Israeli aggression against the strip last summer.

According to the UN�Office for the�Coordination�of�Humanitarian�Affairs in the Occupied Palestinian Territory, over 7,000 unexploded devices, including missiles, still remain in Gaza after Tel Aviv�s war.

Last summer, the Tel Aviv regime launched a brutal attack against the besieged coastal sliver, killing 2,140 Palestinians, including 557 children.

The aggression also left 11,100 Palestinians injured, including 3,374 children and 2,088 women, and displaced over 170,000 others.

Gazans grapple with unemployment, poverty and a declining standard of living on a daily basis as the region has been blockaded since 2007.
