U.N. peacekeepers claim IDF tanks breached their base in southern Lebanon.
The Israel Defense Forces continued intense air and ground campaigns against Hezbollah in Lebanon and against Hamas in the Gaza Strip.
The uptick in offensive operations came days after Israel marked the anniversary of Hamas' Oct. 7 assault and as Israeli leaders planned their response to last week's Iranian ballistic missile attack.
At least 22 people were killed after the Israel Defense Forces shelled a school housing displaced people in the Al-Mufti area, north of Nuseirat, in the central Gaza Strip, the Gaza Health Ministry said Sunday.
Among the deceased were 15 women and children, officials said, and at least 80 others were injured.

At least 67 people have been injured, four critically, near the town of Binyamina, south of Haifa, after a drone strike there Sunday night, according to Israeli emergency services.
Hezbollah claimed the attack, saying it had targeted "a training camp for the Golani Brigade in Binyamina" with a "squadron of attack drones." Israel has not confirmed whether the injured are military or civilian.

During a visit to northern Israel on Sunday, Israeli Defense Minister Yoav Gallant said the Israel Defense Forces will destroy military targets in Lebanon and that "even once IDF troops withdraw, we will not allow Hezbollah terrorists to return."
Gallant described villages in Lebanon along the Israel border as "military targets," saying, "We can see the entire first line of villages with Hezbollah infrastructure."
"These are military targets containing underground tunnels and weapon storages," Gallant claimed.
The IDF released a separate statement about one of its divisions involved in the ground operations, saying its 146th Division’s targeted raids in southern Lebanon had killed "over 100 terrorists" and destroyed dozens of rocket launchers and "command posts."
Meanwhile, the IDF issued a new evacuation order on Sunday for 16 new villages and towns in southern Lebanon, warning people to move north of the Awali River. The order is for 21 areas overall but five of them are repeated from previous orders.
