Israel said the Tuesday attacks were launched after Hamas refused to release more hostages held in Gaza. The strikes raise the prospect of a full resumption of war after a nearly two-month ceasefire.

Israel launched a wave of airstrikes across the Gaza Strip early Tuesday, saying it was hitting Hamas targets in its heaviest assault in the territory since a ceasefire took effect in January. Prime Minister Benjamin Netanyahu said he had ordered the strikes because of a lack of progress in ongoing talks to extend the ceasefire.

C AIRO — Iran on Sunday once again denied aiding Yemen's Houthi rebels after the United States launched a wave of airstrikes against them and President Donald Trump warned that Tehran would be held “fully accountable” for their actions.

The U.S. carried out new airstrikes on Yemen, expanding the biggest U.S. military operation in the Middle East since President Trump took office.

Trump ordered a series of airstrikes on the Houthi-held areas in Yemen, which local authorities said killed at least 53 people, including children.
