Israeli Prime Minister Benjamin Netanyahu said Monday that his country responded “forcefully” to a rocket attack from Gaza that wounded seven people, including three children, near Tel Aviv.

“As we speak, Israel is responding forcefully to this wanton aggression,” Netanyahu said at the White House, where President Trump signed a proclamation recognizing Israel’s sovereignty over the Golan Heights.

“Israel will not tolerate this. I will not tolerate it,” added Netanyahu, who planned to return to Israel to handle the escalating hostilities.

The Israeli offensive began soon after an Egyptian military intelligence delegation left the Gaza Strip, where its attempts to broker a cease-fire failed, the Times of Israel reported.

“At this time, the Israel Defense Forces has started to attack terror targets belonging to the Hamas terror group throughout the Gaza Strip,” the IDF said in a statement shortly after 5:30 p.m. local time.

There were no immediate reports of Palestinian casualties as Israeli drones, helicopters and fighter jets flew over Gaza on Monday evening.

Israeli planes hit a post belonging to Hamas’ military wing, the Izz ad-Din al-Qassam Brigades, with two missiles, reported Shehab, a Gaza-based news outlet.

The IDF earlier in the day deployed two infantry and armored brigades to southern Israel and began a limited call-up of reservists in the intelligence and air defense corps.

The two additional brigades sent to shore up the IDF’s Gaza Division with some 1,000 troops had been conducting training exercises but they were cut short due to the escalation.

IDF Brig. Gen. Ronen Manelis said a rocket that hit the community of Mishmeret was fired by Hamas operatives in Rafiah in the southern part of the strip.

Manelis, who refused to say whether the rocket was fired accidentally or deliberately, said Israel held Hamas responsible, according to Haaretz.

“The launch was carried out by Hamas from one of the group’s launchpads. We see Hamas as responsible for everything that happens in Gaza,” Manelis told reporters.

Hamas’ leader said his group would respond if Israel retaliates too forcefully to the overnight rocket strike.

Ismail Haniyeh said in a written statement Monday that the Palestinian people “will not surrender” and its militant factions “will deter the enemy if it exceeds the red lines.”

A senior Hamas official told Haaretz that the fact that no group had claimed responsibility for the rocket attack means it was either a mistake or an impulsive decision by a trigger-happy fighter.

The rocket left a 60-year-old woman in moderate condition, with her husband suffering light wounds.

A man and woman, both 30, were lightly wounded along with their 3-year-old and 6-month-old, while a 12-year-old neighbor was also lightly wounded.

Meanwhile, Islamic Jihad warned the “Zionist enemy against attacking the Strip,” saying they would “respond with force” to any attack.

A statement said that if Israel strikes the strip, “all Israeli targets will be in the range of fire.”
