Local officials and family members said an Israeli airstrike Tuesday in northern Gaza killed 10 members of Qatar-based Hamas political chief Ismail Haniyeh’s family.

The strike hit a house in the Shati refugee camp west of Gaza City.

Israeli strikes earlier in the war killed three of Haniyeh’s sons.

Israel’s military said its forces carried out airstrikes targeting buildings in Shati and another area in northern Gaza that it said were being used by Hamas militants who were involved in the Oct. 7 attack on Israel.

The latest fighting came as Israel’s Supreme Court ruled that the military must draft ultra-Orthodox Jewish seminary students for military service.

The unanimous decision Tuesday could put additional pressure on Prime Minister Benjamin Netanyahu’s government, which relies on two ultra-Orthodox parties in its coalition.

The war in Gaza and Israel’s clashes with Hezbollah militants along the border with Lebanon have made the issue even more prominent as people questioned the longstanding exemptions that allowed the seminary students to avoid the military service required of most Israeli men and women.

U.S. Secretary of State Antony Blinken on Monday warned Israeli Defense Minister Yoav Gallant against allowing the conflict with Hamas in Gaza to expand to include Lebanon and Hezbollah.

Blinken "underscored the importance of avoiding further escalation of the conflict and reaching a diplomatic resolution that allows both Israeli and Lebanese families to return to their homes," according to a statement from State Department spokesman Matthew Miller.

Blinken also pressed Gallant to take more steps to protect aid workers in Gaza.

The Israeli defense minister will meet with other U.S. officials during his visit to Washington this week, including Defense Secretary Lloyd Austin.

Earlier Monday, European Union foreign policy chief Josep Borrell told reporters in Luxembourg that the risk of the war spilling over is growing bigger every day.

"I think that, unhappily, we are on the eve of the war expanding," Borrell said.

He also said a cease-fire in Gaza is desperately needed to facilitate the flow of humanitarian aid, saying "delivery of humanitarian assistance inside Gaza has become impossible."
