Israeli warplanes launched a series of strikes across Lebanon on Wednesday evening after Hezbollah carried out one of its most intense attacks on Israel since the latest escalation began, with both sides exchanging fire overnight in a sharp widening of the conflict.

The Israeli military said its forces carried out a wave of airstrikes targeting Hezbollah infrastructure across Lebanon. According to the army, within a 30-minute span it destroyed 10 Hezbollah command posts in Beirut’s southern suburbs and dozens of rocket launchers across the country.

The targets included launchers and Hezbollah operatives preparing to fire rockets toward Israel, as well as command centers in the Dahiyeh area used by the group’s intelligence unit and its elite Radwan force, the military said.

The strikes followed a major operation announced by Hezbollah late Wednesday. The Iran-backed group launched successive volleys of rockets and drones at Israeli towns, military bases and other sites, mainly in northern Israel, injuring two people. Most of the projectiles were intercepted or fell in open areas, according to Israeli reports.

Iran’s Islamic Revolutionary Guard Corps said it had carried out a joint missile operation with Hezbollah against targets inside Israel. In statements carried by the Fars News Agency and Tasnim News Agency, the Guards said the “joint and integrated operation” targeted more than 50 locations, including Israeli military bases in Haifa, Tel Aviv and Beersheba.

Hezbollah said the attack — dubbed “Operation Chewed Wheat,” a reference to a Quranic verse about reducing one’s enemies to chewed wheat — involved coordinated missile and drone fire alongside Iranian missiles.

Early Thursday, Hezbollah claimed it had fired advanced missiles at the Glilot base in the suburbs of Tel Aviv, which houses the headquarters of Israel’s Unit 8200 military intelligence division.

Moreover, an Israeli strike early Thursday on the seafront area of Ramlet al-Bayda in central Beirut killed at least seven people and wounded 21 others, Lebanon’s health ministry said in an initial statement. The strike targeted a car along the coastal road, according to the state-run National News Agency.

Local media footage showed smoke rising above the seaside promenade after the attack. It was the third strike in the heart of the Lebanese capital since the conflict began.

In the hills overlooking Beirut, Israeli strikes early Thursday on the town of Aramoun killed three people and wounded a child, the ministry said. The town, about 10 kilometers south of the capital, has been sheltering dozens of displaced families and has been targeted twice since Hezbollah fired rockets into northern Israel on March 2.

Israeli strikes also hit several towns in southern Lebanon, including Taybeh, Al-Sultaniyya and Qana near the coastal city of Tyre, the National News Agency reported.

Lebanese authorities say Israeli strikes have killed at least 634 people and wounded 1,586 in less than 10 days of fighting. More than 816,700 families have registered as displaced with the Lebanese government, though officials say the true number is likely higher.

Around 126,000 displaced people are staying in collective shelters, while many others have been sleeping in tents or in the open, including along the seafront at Ramlet al-Bayda.

Israeli officials have meanwhile signaled the possibility of widening their campaign against Hezbollah. Israel’s security cabinet met Wednesday night to discuss the situation in Lebanon, where officials said they were seeking to stop the group’s ability to launch rockets into Israeli territory.

The Israeli newspaper Yedioth Ahronoth reported that the Israeli military has increased the number of its positions in southern Lebanon from five to 18. The paper quoted military officials as saying the campaign against Hezbollah would not be short and would not be bound by a specific timetable, adding that Israel is applying the Gaza model in Lebanon.

Separately, sources told Al Hadath that the Lebanese State has not received any assurances that government facilities will not be targeted.
