Threat of Israel-Hezbollah war looms after Lebanon device explosions

(LONDON) — The threat of a wider war is looming over the Israel-Lebanon border after two consecutive days of explosions across Lebanon and in Syria, confirmed to have killed at least 32 people.

Prime Minister Benjamin Netanyahu restated his intention of returning tens of thousands of displaced Israelis to their homes in the north of the country, parts of which have been emptied by the threat of Hezbollah attacks.

Defense Minister Yoav Gallant, meanwhile, said the “center of gravity” of Israel’s 11-month-old war against Hamas and its backers “is shifting” from the Gaza Strip to the northern border with Lebanon.

The Israeli rhetoric was punctuated by two waves of explosions in Lebanon.

Pager devices exploded on Tuesday prompting chaos in the capital Beirut and across the Hezbollah militant group’s southern heartland. On Wednesday, walkie-talkies exploded, some during funeral processions being held for militants killed in Tuesday’s explosions.

An ABC News source confirmed that Israel was behind the Tuesday pager attacks. Israeli leaders have not publicly commented on either round of explosions.

The Lebanese Health Ministry said that at least 32 people — including two children — were killed across the country. More than 3,250 people were injured, it said.

Hezbollah said 20 of its members were killed in Wednesday’s walkie-talkie explosions. Another 11 were killed in Tuesday’s pager explosions in Lebanon and Syria, bringing the overall death toll for the group to 31.

The Iranian-backed group blamed Israel for both waves of explosions and vowed a “reckoning.” Hezbollah leader Hassan Nasrallah is due to address the situation in a public address on Thursday afternoon.

The militant group claimed several retaliatory strikes into Israel this week — including on Thursday morning — with Israel Defense Forces warplanes and artillery responding.

Cross-border fire has been near-constant since Oct. 8, when Hezbollah began attacks in protest of the IDF operation into the Gaza Strip — the response to Hamas’ Oct. 7 infiltration attack into southern Israel.

But as Gallant told reporters on Wednesday, “I believe that we are at the onset of a new phase in this war.”

A source confirmed to ABC News on Wednesday that Israel’s 98th Division is being deployed from Gaza battlefields to the north of the country.

“We are determined to change the security reality as soon as possible,” Maj. Gen. Ori Gordin, head of the IDF’s Northern Command, said. “The commitment of the commanders and the troops here is complete, with peak readiness for any task that will be required.”

The war, U.S. officials have long warned, could spiral into a broader conflict involving Iran — a prime benefactor of both Hezbollah and Hamas.

Notable casualties demonstrated the multinational nature of the crisis. A detonating pager injured at least 14 people in Syria, where both Hezbollah and Iranian forces have been active for several years in support of its president, Bashar al-Assad.

Iran’s ambassador to Lebanon, Mojtaba Amini, was also among the thousands injured, Iranian officials said. Tehran “will duly follow up on the attack against its ambassador in Lebanon,” the country’s ambassador to the United Nations said in a letter to U.N. leaders on Wednesday.

Israel and Iran have already exchanged significant strikes since Oct. 7. Israel assassinated a top Islamic Revolutionary Guards Corps commander, Mohammad Reza Zahedi, in Syria in April and Hamas leader Ismail Haniyeh in Tehran in July. Iran fired a huge barrage of drones and missiles toward Israel in response to Zahedi’s killing.

This week’s bombings in Lebanon raised the possibility of further action, whether overt or covert. Police announced on Thursday that an Israeli citizen was arrested on suspicion of working with Iranian intelligence to assassinate leaders including Netanyahu and Gallant.

Secretary of State Antony Blinken reiterated U.S. appeals for calm during a press conference in Egypt on Wednesday, where he traveled for fresh Gaza cease-fire talks.

“Broadly speaking, we’ve been very clear, and we remain very clear about the importance of all parties avoiding any steps that could further escalate the conflict that we’re trying to resolve in Gaza,” Blinken said.

A conflict spreading to other fronts, he added, is “clearly not in the interest of anyone involved.”

The U.S., Blinken and other American officials said, were not involved in or pre-briefed on the remote explosions that rocked Lebanon on Tuesday and Wednesday.

Gallant spoke with Defense Secretary Lloyd Austin three times in two days, the latest conversation on Wednesday reaffirming the “unwavering U.S. support for Israel in the face of threats from Iran, Lebanese Hezbollah, and Iran’s other regional partners” and the need for de-escalation, a Pentagon readout said.

U.S. officials were notified by Israeli counterparts on Tuesday that they were planning an operation against Hezbollah, but did not provide any details about what they were going to do, U.S. officials said.
