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.
The Israel Defense Forces said Hezbollah struck one of its bases Sunday, killing at least four soldiers.
Another seven soldiers were "severely injured," according to the IDF statement.
"The IDF shares in the grief of the bereaved families and will continue to accompany them," the IDF said.
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.
