The Israeli army warned Gazans Tuesday to evacuate areas near the border, after it unleashed a wave of deadly overnight strikes, the most intense since a ceasefire began in January.

In a post on X, Israeli military spokesman Avichay Adraee issued a warning to residents "specifically in the neighborhoods of Beit Hanoun, Khirbet Khuza'a, Abasan al-Kabira and Al-Jadida". "These designated areas are considered dangerous combat zones... For your own safety, you must evacuate immediately to the known shelters in western Gaza City and those in Khan Yunis," the post said.

U.S. President Donald Trump has declared that he will hold Iran directly responsible for any future attacks by Yemen's Tehran-backed Houthi rebels, who have targeted U.S. and other foreign ships in the Red Sea.

Yemen's Houthi rebels condemned on Tuesday Israel's wave of strikes on Gaza, vowing to escalate its own operations in support of its ally Hamas after threatening to renew attacks on Israeli shipping in the Red Sea.

Israel vowed on Tuesday to continue fighting in Gaza until the return of all hostages as it unleashed its most intense strikes since a ceasefire, killing at least 413 Palestinians, including women and children, according to hospital officials.

Hamas accused Israeli Prime Minister Benjamin Netanyahu of deciding to "resume war" after a deadlock on extending the truce, and warned that the return to fighting could be a "death sentence" for hostages still alive in Gaza.

Israeli strikes hit several sites in southern Syria overnight, including in the city of Daraa.

The Israeli military said it was hitting “command centers and military sites containing weapons and military vehicles belonging to the old Syrian regime, which (the new army) are trying to make reusable.”

The United States and Iran-backed Houthi rebels in Yemen are both vowing escalation after the U.S. launched airstrikes to deter the rebels from attacking military and commercial vessels on one of the world's busiest shipping corridors.

The Houthi-run Health Ministry said the U.S. strikes killed at least 53 people, including five women and two children, and wounded almost 100 in the capital of Sanaa and other provinces, including Saada, the rebels' stronghold on the border with Saudi Arabia.

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."

The European Union hosts a donor conference for Syria on Monday to muster support to ensure a peaceful transition after President Bashar Assad was ousted by an insurgency last December.

Ministers and representatives from Western partners, as well as Syria's regional neighbors, other Arab countries and U.N. agencies will take part in the one-day meeting in Brussels which will be chaired by EU foreign policy chief Kaja Kallas.

Yemen's Iran-backed Houthi rebels claimed responsibility on Monday for a second attack on an American aircraft carrier group in 24 hours, calling it retaliation for U.S. strikes.

A spokesperson for the group said "for the second time in 24 hours" Houthi fighters launched missiles and drones at the USS Harry S. Truman and several of its warships in the northern Red Sea.
