At least 4 Gazans were martyred and dozens others were injured as an unexploded missile from the Israeli regime’s last year war against the besieged Gaza Strip went off in the coastal enclave's south.

Palestinian medical sources in the southern city of Rafah said that the number of martyrs may rise as some injured are in critical condition.

The explosion took place inside a house in Al-Shabura (refugee) camp near Rafah, Palestinian sources said.

The United Nations Humanitarian Coordinator for the Palestinian territories says more than 7,000 unexploded weapons, including dozens of missiles, remain in Gaza following Israel’s 50-day war on Gaza, which started on July 7, 2014.

Over 2,130 Palestinians lost their lives and some 11,000 others were injured in the war. Gaza Health officials say the victims included 578 children and nearly 260 women.

About 1,500 buildings and structures were also demolished during the Israeli offensive. Many Gazans remain homeless.

Gazans are also struggling against a blockade imposed by Israel since June 2007, which has caused a decline in the standard of living, unprecedented levels of unemployment and unrelenting poverty.
