An elderly couple was killed on Tuesday night after Iran launched cluster bomb strikes on Ramat Gan.
The pair, who were in their 70s, were reportedly making their way to a bomb shelter when the projectiles hit.
Another two people are being treated for light shrapnel wounds sustained in the strike.
Cluster bombs contain dozens of smaller explosives, known as bomblets, which disperse across a wide area before impact.
The IDF estimates that around 50 per cent of all missiles launched by Iran at Israel since the start of the war have been fitted with cluster warheads, allowing a single missile to cause indiscriminate damage in multiple locations.
More than 100 countries have prohibited the proliferation or use of such munitions since 2008 under the Convention on Cluster Munitions (CCM), but the US, Israel and Iran are not signatories.
Nonetheless, their use on civilian targets or in populated areas is widely regarded as a violation of international law and, potentially, a war crime.
Footage released by the Associated Press showed the moment the missiles fired at Ramat Gan separated into bomblets, suggesting a cluster bomb was employed.
The Islamic Revolutionary Guard Corps (IRGC) confirmed that the attacks were launched in retaliation for the Israeli strike which killed Ali Larijani, the secretary of the National Security Council and a former speaker of the Iranian parliament.
Larijani was considered the right-hand man of the late supreme leader, Ayatollah Ali Khamenei before the latter’s death in another Israeli strike earlier in the war.
In his role as head of the Islamic Republic’s security forces, he was widely regarded as responsible for the brutal suppression of dissent in the country, notably the crushing of anti-regime protests earlier this year, which left tens of thousands dead.
The IDF also confirmed that a separate strike on an Iranian tent camp eliminated Gholamreza Soleimani, the commander of the Basij paramilitary force.
The Basij is one of the five main branches of the Islamic Revolutionary Guard Corps (IRGC) and is commonly known as Iran’s “morality police”, enforcing Islamic law on the population.
The same strike killed Soleimani’s deputy and other top Basij officials, per the IDF.
