The Israeli army’s chief spokesman, Rear Adm. Daniel Hagari, has said the Hezbollah attack on Israeli civilians on Sunday was “very serious.”

Hezbollah had wounded Sunday seven Israeli troops and 10 employees who were in Dovev to repair power lines downed by earlier strikes, according to Israel. Hezbollah said the guided missiles targeted a “logistical force belonging to the occupation army that was about to install transmission poles and eavesdropping and spying devices near the Dovev barracks.” Some of the wounded are in critical condition.

The Israeli army is preparing to deal a “strong blow” to Hezbollah in response to the escalation of its attacks today, Israeli right-wing newspaper Maariv said on Sunday.

An Israeli army spokesman later said that a fighter jet and other aircraft attacked several Hezbollah targets in Lebanon, including "a military compound containing a warehouse of weapons and military infrastructure."

The United Nations peacekeeping force in Lebanon said gunfire from an unidentified source hit a member of its contingent early Sunday, adding that the peacekeeper was in a stable condition.

Israeli fighter jets pounded suspected Hezbollah targets in southern Lebanon with air strikes on Sunday, after an incoming anti-tank missile wounded 10 Israeli civilians near the border, the Israeli army said.

The Israeli army said "a number of civilians were wounded" in the anti-tank missile strike near the village of Dovev, just half 800 meters from the frontier with Lebanon.

Israeli artillery shelling on Sunday targeting the outskirts of the southern Lebanese border towns of Shihin, Umm al-Tout, Halta and Kfarshouba.

The Israeli army radio meanwhile said a rocket fired from south Lebanon landed in an open area in the Western Galilee in northern Israel.

Iranian President Ebrahim Raisi told caretaker Prime Minister Najib Mikati during a bilateral meeting in Riyadh that Hezbollah is “independent in decisions and actions and does not receive orders from Iran.”

“Hezbollah’s measures in south Lebanon are based on wisdom, rationality and deterrence in order to prevent aggression,” Raisi added.

Hezbollah has been trading daily cross-border fire with its sworn enemy Israel as war rages in Gaza, with the Iran-backed Lebanese group deploying a large weapons arsenal amassed over decades.

Below is a look at the group's firepower and how it has expanded since it fought a war with Israel in 2006.

Two people arrested in Brazil for allegedly planning attacks in the country on behalf of Lebanon-based Hezbollah have denied any such involvement, according to images seen on the G1 news site.

During an audience with a judge conducted by videoconference, the suspects -- both Brazilian nationals in their 30s arrested earlier this week by federal police -- categorically denied all charges, calling them "absurd."

An Israeli drone strike has killed an Amal Movement fighter and wounded two others, according to a statement released by Amal, which is allied with Hezbollah.

Ali Daoud became the first Amal fighter to be killed in action since the fighting began on October 8, while Hezbollah has lost nearly 70 fighters during the past five weeks.

Israeli Defense Minister Yoav Gallant has warned Hezbollah that launching a war would result in widespread destruction in Lebanon similar to that in Gaza, where Israel is battling Hamas militants.

"If it (Hezbollah) makes this kind of mistake here, the ones who will pay the price will be first and foremost Lebanese citizens," Gallant told soldiers on Israel's northern border in remarks relayed by his office.
