Israeli strikes kill over 400 in Gaza, say Palestinians, threatening total truce collapse

Israeli airstrikes pounded Gaza, killing more than 400 people, Palestinian health authorities said on Tuesday, threatening the complete collapse of a two-month ceasefire as Israel vowed to use more force to free hostages held by Hamas.

The Palestinian militant group, which still holds 59 of the 250 or so hostages seized in its October 7, 2023 attack on Israel, accused Israel of breaching the ceasefire and jeopardising efforts by mediators to secure a permanent truce.
