The United States under President Donald Trump has launched a new campaign of intense airstrikes targeting Yemen's Houthi rebels.

This weekend's strikes killed at least 53 people, including children, and wounded others. The campaign is likely to continue, part of a wider pressure campaign by Trump now targeting the Houthis' main benefactor, Iran, as well.

Israeli Prime Minister Benjamin Netanyahu has said he will seek to dismiss the head of the internal security service this week, deepening a power struggle focused largely on who bears responsibility for the Hamas attack that sparked the war in Gaza.

Netanyahu's effort to remove Ronen Bar as director of the Shin Bet comes as the security service investigates close aides of the prime minister. Netanyahu said he has had "ongoing distrust" with Bar, and "this distrust has grown over time."

New Canadian Prime Minister Mark Carney met with French President Emmanuel Macron on Monday, seeking support from one of Canada's oldest allies as U.S. President Donald Trump continues to attack Canada's sovereignty and economy.

U.S. President Donald Trump said he ordered a series of airstrikes on the Houthi-held areas in Yemen on Saturday, promising to use "overwhelming lethal force" until the Iran-backed rebels cease their attacks on shipping along a vital maritime corridor. The Houthis said at least 31 people were killed.

"Our brave Warfighters are right now carrying out aerial attacks on the terrorists' bases, leaders, and missile defenses to protect American shipping, air, and naval assets, and to restore Navigational Freedom," Trump said in a social media post. "No terrorist force will stop American commercial and naval vessels from freely sailing the Waterways of the World."

Ordnance from Syria's 13-year conflict exploded in the coastal city of Lattakia, collapsing a building and killing more than a dozen people, the Syrian Civil Defense said Sunday.

The group and residents said the explosion occurred in a metal scrap storage space on the ground floor of the four-story building.

The rebels said one strike hit two homes in northern Saada province, killing four children and a woman. The rebel-run Al-Masirah TV showed images of what it said were the bodies.
