The NGO Humanity & Inclusion has been working for decades to protect civilians from explosive weapons and has repeatedly warned about the dangers posed by the presence of Israeli explosive remnants of war in the Gaza Strip. The consequences of which are far-reaching: loss of life, disabling injuries, psychological trauma and delayed deliveries of humanitarian aid and reconstruction efforts.
For more than five months, the Israeli army has been pounding the Gaza Strip in retaliation for the Hamas-led October 7 attack on Israel.
While Prime Minister Binyamin Netanyahu has vowed to annihilate the Islamist movement governing the Palestinian territory, Israeli bombing has ravaged the Gaza Strip, killing more than 30,000 people, according to the Gaza health ministry.
In addition to the daily intensive shelling and the famine that threatens to spread throughout the coastal strip already experiencing a major humanitarian crisis, unexploded ordnance is an equally lethal danger hanging over the Gazan population.
Explosive remnants of war (ERW) are munitions that have failed to explode on impact during a conflict, either due to a technical malfunction or because they were deliberately programmed to detonate at a later date.
"Missiles, rockets, artillery shells, cluster munitions...These are all munitions that did not explode when they were launched or that are programmed to explode later and trap people or vehicles, such as anti-personnel mines and anti-tank mines," says Anne Héry, advocacy director at NGO Humanity & Inclusion. "These explosive remnants of war, which are extremely dangerous for anyone who comes into contact with or is close to them, continue to kill and mutilate people during and long after a conflict has ended and prevent displaced people from returning home."
More than 2 million people trapped
Humanity & Inclusion has been working for several decades with populations exposed to the dangers of weapons, munitions and explosive devices in armed conflicts. It has repeatedly warned about explosive contamination amid the ongoing war in the Gaza Strip.
"In Gaza, the population is being subjected to one of the most intense bombing campaigns in military history," says Héry. "The number of strikes, bombings and artillery fire is absolutely phenomenal in terms of pace and concentration. According to our estimates, over the course of this five-month war, we are now at a rate of 500 bombs a day."

Héry points out that the Palestinian enclave is one of the most densely populated areas in the world and one of the most vulnerable because of the extent of the destruction caused by the bombardments, which have destroyed critical civilian infrastructure.
"It is a territory from which the 2.2 million inhabitants cannot flee and in which they find themselves trapped and subjected to extremely intense bombardments day and night," she adds. By way of comparison, the Gaza Strip (360 square kilometres) is about twice the size of Washington, DC (177 square kilometres) and one-quarter the size of Greater London (1,579 square kilometres), but much more densely populated.
An area already impacted by previous conflicts
Civilians account for 90% of the victims of explosive weapons when they are used in populated areas, says Humanity & Inclusion. Furthermore, it is very difficult to know the full extent of contamination caused by the remnants of war in Gaza because the conflict is still ongoing.
"An estimated 45,000 bombs were dropped on the Gaza Strip in the first three months of the conflict. However, based on a failure rate of between 9% and 14%, it is possible that several thousand bombs did not work as planned and did not explode on impact, ending up scattered in the ruins and all over the territory," says Héry.
According to Humanity & Inclusion, ERW is likely to cost more lives in Gaza and cause complex and disabling injuries – whether temporary or permanent – that require immediate medical attention, which is often impossible during war time.
"Some injuries caused by explosive remnants of war require lifelong support, not to mention the psychological trauma that affects victims, sometimes entire communities, for many years," says Héry. "And not just when you've been a victim or lost loved ones, but also when you've lived for weeks in fear of the bombs."
It is also important to remember that the Gaza Strip was already contaminated by the ERW left over from previous conflicts between Hamas and the Israeli army.
"The Palestinian territory has been bombed many times in recent decades, so there was already a major problem of certain areas being contaminated before the current war," says Héry. "Given that Gazans don't have the means to clean up their territory themselves, heavy, complex and costly resources will need to be used to deal with this significant increase in explosive contamination."
"Any conflict generates explosive remnants of war, which can remain underground in ruins for decades. In Syria and Ukraine’s cases, it will take several decades to clean up," adds Héry.
Long-term pollution
This is a global scourge as one in every two countries in the world is affected by ERW, according to Humanity & Inclusion. Syria, Afghanistan, Libya, Ukraine, Iraq and Yemen are the most contaminated nations, as vast swathes of their territories have been bombed and shelled over the long term.
"Even today in France, bombs dating back to World War I are still being found and mine clearance operations are still underway in Laos, even though the contamination dates back to the Vietnam War," says Héry. "So we can imagine that it will take an extremely long time to clear up the pollution in Gaza once a ceasefire has been agreed."
This long-term pollution is likely to have a heavy and lasting impact on the daily lives of the people of Gaza, Humanity & Inclusion’s advocacy director explains. Given Gaza’s urban environment – where buildings have collapsed, are in ruins or damaged – explosive remnants are not only a permanent danger, but will also have a long-term impact on Gazans’ daily lives and their territory’s socio-economic development.
"When it comes to clearing away layers of rubble strewn with potentially fatal remnants, which our mine clearance specialists have described in certain Syrian towns affected by the war as a torrent of bombs, or when it comes to rebuilding, it is extremely dangerous," says Héry. "In the long term, these explosive remnants have an extremely strong impact because they hamper reconstruction, the delivery of humanitarian aid and the resumption of economic life by contaminating all access routes, restricting movement and rendering agricultural land and public or state infrastructure unusable."
This difficult situation is causing frustration and risky behaviour.
"The situation in Gaza is so desperate from a humanitarian perspective, due to very poor access to water and famine, that people sometimes want to return to their destroyed homes to find food, at the risk of adopting sometimes extremely dangerous behaviour that is exacerbated in contexts of extreme scarcity," says Héry. "Our teams are trying to warn the population, through prevention and information campaigns on the dangers of war remnants."
As Israel is not a signatory to the Ottawa Treaty banning anti-personnel mines, the Convention on Cluster Munitions or the Political Declaration on the Use of Explosive Weapons in Populated Areas, Humanity & Inclusion believes that it is obliged to do so under international humanitarian law.
"International humanitarian law requires States and belligerents to take every precaution to protect civilians, to avoid directly targeting people, buildings, equipment and property, and to ensure that there is no disproportionate damage to people or property in relation to the military advantage anticipated," says Héry.
