Israeli strikes latest bloody chapter in war of extraordinary civilian casualties

International rules of combat to deter impact on noncombatants have been loosened or ignored - and other regimes may follow

It is a casualty rate that would have unimaginable before the start of the Israel-Hamas war. More than 400 Palestinians have been reported killed after 10 hours of resumed Israeli airstrikes on Tuesday, including, according to one early report, at least six members of one family in an attack on a car east of Khan Younis.

Though it is too soon to determine how many noncombatants died in attacks that Israel says were directed at Hamas military commanders and political officials (casualty totals from Gaza's health ministry do not distinguish combatants from the uninvolved), the likelihood is that civilians will have been killed in large numbers.
