More than 200 Palestinians were killed in overnight Israeli strikes on the Gaza Strip, the Hamas-ruled enclave's Ministry of Health said, as Hamas accused Israel of violating a fragile ceasefire deal.

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.

Under former President Joe Biden, the U.S. and the United Kingdom began a series of airstrikes against the Houthis starting in January 2024. A December report by The International Institute for Strategic Studies said the U.S. and its partners struck the Houthis over 260 times up to that point.

U.S. President Donald Trump said on Monday he would hold Iran responsible for any attacks carried out by the Houthi group that it backs in Yemen, as his administration expanded the biggest U.S. military operation in the Middle East since Trump returned to the White House.
