Israeli airstrikes and artillery fire continued across southern Lebanon on Tuesday as tensions escalated further along the border, while Israeli media and military statements pointed to a widening campaign targeting Hezbollah infrastructure across the country.

The Israeli military said it carried out overnight strikes on more than 100 Hezbollah sites and operatives in the Beqaa Valley in eastern Lebanon and across the south, marking one of the most extensive reported waves of strikes in recent weeks.

According to the Israeli military, the targets included weapons depots, command centers, observation posts and other infrastructure used by Hezbollah to plan and carry out attacks against Israeli troops and civilians.

In a separate statement, the military said that in one strike in the Mashghara area of the Beqaa Valley, it targeted infrastructure where Hezbollah operatives had been identified, killing them in a series of rapid successive strikes carried out within seconds.

Israeli officials have also warned of further escalation, including the possibility of renewed strikes on Beirut’s southern suburbs, as military activity intensified across multiple fronts.

Israeli public broadcaster reported that the Israeli military has issued emergency reserve call-up orders as part of preparations to expand operations beyond the so-called “yellow line” in southern Lebanon. The broadcaster said the military has begun mobilizing forces to intensify its campaign and ordered recently discharged soldiers to immediately return to reserve duty.

Israeli Channel 15 reported that the area of Rosh HaNikra, near the Lebanese border, was declared a closed military zone until at least May 31 following the latest escalation in the north.

Channel 13 reported that Israel’s security cabinet was expected to hold a meeting to discuss the situation in Lebanon as well as broader regional developments, including the possibility of an emerging agreement involving Iran.

The Israeli military issued on Tuesday an evacuation warning for the southern Lebanese city of Nabatiyeh ahead of planned airstrikes targeting what it described as Hezbollah infrastructure.

Residents were instructed to move north of the nearby Zahrani River.

“In light of the Hezbollah terror organization’s violations of the ceasefire agreement, the IDF is forced to act against it with force and does not intend to harm you,” Israeli military spokesman Col. Avichay Adraee said in a warning directed at civilians.

On the ground, Israeli warplanes carried out three overnight airstrikes on the towns of Srifa, Shhour and Arzoun. In Arzoun, the home of the town’s mayor was completely destroyed, according to local reports.

Further strikes hit multiple areas across the south, including Yohmor al-Shaqif, Braachit, the Wadi neighborhood of Doueir, and the outskirts of Haris. Other targeted locations included Barish, Kafra, Deir al-Zahrani, Kawthariyet al-Riz, Ghandouriyeh, Frun, Housh, and surrounding areas.

Heavy artillery shelling also targeted several towns, including Kafra, Qaqaiyet al-Jisr, Shhour, Srifa, Arnoun, Yohmor al-Shaqif, Zawtar al-Sharqiyeh and Mifdoun, as well as areas near the Beaufort Castle rest site.

The town of Mifdoun was also struck repeatedly since dawn by Israeli air raids, according to local reports.

Separate strikes were reported in Majdal Selem and Kfarsir, while artillery fire also hit Hadatha.

Earlier in the morning, Israeli aircraft targeted the industrial zone near Tyre at the Maarka junction, striking a building that had reportedly been threatened by the Israeli military a day earlier.

The death toll from overnight strikes on the town of Machghara rose to 12, including Sheikh Hussein Rizk, with several others wounded. Rescue teams continued clearing rubble from the site as search operations went on.

On the Israeli side, media reports said a Hezbollah drone exploded near Baranit without causing any injuries.
