Israeli strikes in Gaza kill top Islamic Jihad leaders and civilians.

Israel launched surprise strikes across Gaza, killing three leaders of the Islamic Jihad organization and several other civilians, prompting a promise of swift retaliation from militant groups and leaving the region braced for an escalation of violence. At least 13 people were killed, including four women and four children, the Palestinian Ministry of Health said, adding that 20 others were injured. Armed Palestinian groups responded with warnings of repercussions, raising the possibility of a longer, drawn-out conflict.
