At least four Palestinians were killed and more than 30 injured on Thursday when unexploded ordnance from Israel's military assault on Gaza last summer blew up while Palestinian workers were helping family members clear out remaining rubble from a destroyed home in Rafah, in the south of the Gaza Strip, Gaza Health Ministry spokesman Ashraf al-Qidra said.
Four dead bodies and people with multiple injuries arrived at the emergency room of Abu Yousif al-Najjar hospital in Rafah, Palestinian medical sources at the hospital stated.
Twitter reports suggest that the victims were all members of the Abo Naqira family.

Over 7,000 unexploded bombs were left throughout the Gaza Strip following last year's 50-day war between Israel and Palestinian resistance group Hamas, according to officials of the UN Humanitarian Coordinator for the Palestinian territories (OCHA).
Last year, six people, including an Associated Press video journalist and his Palestinian translator, were killed and three people, including an AP photographer, were badly injured after a bomb exploded when Gaza police engineers tried to defuse the device.
Even before the most recent Israeli attack on the Gaza Strip, unexploded ordnance from Israel's offensives in 2008, 2009 and 2012 posed a major threat to local residents.
One hundred and eleven civilians, 64 of them children, were victims of unexploded ordnance in the Gaza Strip between 2009 and 2012, reaching an average of four casualities per month in 2012 according to a report published in the same year by the Office of the United Nations High Commissioner for Human Rights.
The 2014 war in Gaza saw over 2,100 Palestinians killed, most of whom were civilians, as well as the deaths of 67 Israeli soldiers and six Israeli civilians. Over 16,245 homes were destroyed in the war, which lasted for 50 days before coming to an end with a cease-fire in August.
