More than 76,000 people have been displaced in Lebanon in almost three months of near-daily fighting along the border with Israel, the U.N.'s International Organization for Migration has said.

The border area has seen a surge of violence since the Israel-Hamas war broke out in early October, with tit-for-tat exchanges of fire continuing on Friday between Israeli forces and Hezbollah.

Caretaker Prime Minister Najib Mikati met Friday with head of the Catholicosate of the Great House of Cilicia, His Holiness Catholicos Aram I, in Antelias.

Mikati and Aram I discussed issues and challenges facing Lebanon, particularly the situation in the South of Lebanon, the presidential election, and the socio-economic crisis facing the country, the Armenian Church Catholicosate of Cilicia said.

EU's foreign policy chief Josep Borrell, will arrive Friday in Lebanon on a three-day visit.

Borrell will meet with Parliament Speaker Nabih Berri, caretaker Prime Minister Najib Mikati, caretaker Foreign Minister Abdallah Bou Habib and Lebanese Army Commander General Joseph Aoun.

Clashes continued on Friday between Israeli forces and Hezbollah, as tensions rose further after a strike on Tuesday killed Hamas's number two, Saleh al-Arouri, in a Hezbollah stronghold in south Beirut.

Israeli warplanes struck the outskirts of the southern towns of Majdalzoun and Mhaibib and a region near a Lebanese army position in Aita al-Shaab, while shells hit the border towns of Houla, Tayr Harfa, al-Jebbayn, Rashaya al-Foukhar, Fardis, al-Bustan and Yarin.

U.S. Secretary of State Antony Blinken and French Foreign Minister Catherine Colonna agreed to seek steps to avoid a wider Middle East war following strikes in Lebanon and Iran, the State Department said.

In a telephone call the day before, the two top diplomats "discussed the importance of measures to prevent the conflict in Gaza from expanding, including affirmative steps to de-escalate tensions in the West Bank and to avoid escalation in Lebanon and Iran," State Department spokesman Matthew Miller said.

Thousands of people took to the streets in Beirut Thursday the funeral of Saleh Arouri, top commander of the militant Palestinian group Hamas, who was killed earlier this week in an apparent Israeli airstrike in the Lebanese capital.

Draped in Palestinian and Hamas flags, Arouri's coffin along with those of two of his comrades were first taken to a Beirut mosque for prayers before being carried to the Palestine Martyrs Cemetery where top Palestinian officials killed by Israel over the past five decades have been buried. Arouri's automatic rifle was placed on his coffin at the prayer service.

U.S. mediator Amos Hochstein arrived in Israel Thursday where he held a meeting with Defense Minister Yoav Gallant, ahead of a possible visit to Lebanon.

Fears have mounted that Israel's war in Gaza could spread across the region after strikes in Lebanon and Iraq as well as deadly blasts in Iran, but experts say a wider conflict is unlikely for now.

What has happened?

Caretaker Prime Minister Najib Mikati received a phone call Wednesday evening from French Foreign Minister Catherine Colonna.

Hezbollah targeted Thursday Israeli soldiers and posts in Shtula, Metula, al-Manara and al-Jerdah while Israel struck the outskirts of Houla and Maroun al-Ras and shelled al-Khiam and the Panorama curve -- between Kfarkila and Odeisseh -- with white phosphorus bombs.

Four Hezbollah fighters, including a local Hezbollah leader, were killed overnight in southern Lebanon in Israeli strikes on the border town of Naqoura.
