Gaza health officials say Israeli airstrikes have killed at least 19 people including six children at a water collection point.

Six children waiting for water are among those killed in an Israeli air strike, emergency service officials say.

Amos Guiora, a law professor at the University of Utah where he directs the Bystander Initiative, centered his pointed remarks on “enablers,” those in the Israeli government he sees as allowing Prime Minister Benjamin Netanyahu to “abandon” those Hamas still holds captive.

Israel’s military said a “technical error” had caused munition to land dozens of meters from its target. The victims were gathered near a water distribution point, health workers said.

At least 82 Palestinians, including children and people fetching water, were killed Sunday in a series of Israeli airstrikes targeting residential areas and displacement tents across the Gaza Strip, according to medical sources.

Iran's Fars news agency claimed President Masoud Pezeshkian was targeted in an Israeli airstrike similar to one that killed Hezbollah leader Nasrallah.

Iran's Fars news agency says President Masoud Pezeshkian had a leg injury when his secret site was hit in June.

US and Israeli air defences failed to defend Israeli cities against Iran's missile barrage in the 12-day war. Israel's Iron Dome and US' advanced THAAD and Patriot air defence systems were rendered useless as Iran pounded Israel with hundreds of missiles nearly everyday.

The Israeli military said it intended to hit an Islamic Jihad militant in the area, but that a malfunction had caused the missile to fall "dozens of metres from the target."
