Hezbollah targets in a disputed area where the borders of Israel, Lebanon and Syria meet.

Hezbollah claimed responsibility on Sunday for strikes on Israeli positions in disputed area along the border with Syria’s Golan Heights, and Israel’s military said it struck Hezbollah targets in a disputed area where the borders of Israel, Lebanon and Syria meet with armed drones, raising the prospect of a broader conflict as Israel continued to battle Hamas fighters a day after an unprecedented surprise attack in Israel’s south.

Around 3am, a loudspeaker atop a mosque in Gaza City blared a stark warning to residents of nearby apartment buildings: Evacuate immediately. Just minutes later, an Israeli airstrike reduced one nearby five-story building to ashes.

After one Israeli strike, a Hamas rocket barrage hit four cities, including Tel Aviv and a nearby suburb. Throughout the day, Hamas fired more than 3,500 rockets, the Israeli military said.

The shadowy leader of Hamas’ military wing, Mohammed Deif, said the assault was in response to the 16-year blockade of Gaza, and a series of recent incidents that have brought Israeli-Palestinian tensions to a fever pitch.

Over the past year, Israel’s far-right government has ramped up settlement construction in the occupied West Bank, Israeli settler violence has displaced hundreds of Palestinians there, and tensions have flared around the Al-Aqsa mosque, a flashpoint Jerusalem holy site.

"Enough is enough,” Deif, who does not appear in public, said in the recorded message. He said the attack was only the start of what he called "Operation Al-Aqsa Storm” and called on Palestinians from east Jerusalem to northern Israel to join the fight.

The Hamas incursion on Simchat Torah, a normally joyous day when Jews complete the annual cycle of reading the Torah scroll, revived painful memories of the 1973 Mideast war practically 50 years to the day, in which Egypt and Syria launched a surprise attack on Yom Kippur, the holiest day of the Jewish calendar, aiming to take back Israeli-occupied territories.
