President Joseph Aoun stressed Monday that “the army is responsible for protecting the border and it enjoys readiness.”

Iran said on Monday that it will take part in this weekend's funeral of Sayyed Hassan Nasrallah, the slain leader of Lebanon's Tehran-backed Hezbollah movement, with a senior delegation.

"We will participate in this ceremony at a high level," Iranian foreign ministry spokesman Esmaeil Baqaei told reporters, without specifying who would attend Sunday's ceremony in Beirut.

Lebanese President Joseph Aoun urged on Monday sponsors of a ceasefire deal between Israel and Hezbollah to help pressure Israel to withdraw troops by a deadline the following day.

"We are continuing contacts on several levels to push Israel to respect the agreement and to withdraw on the scheduled date, and return the prisoners," Aoun said, according to a presidency statement.

An Israeli strike targeted Monday a vehicle in the southern city of Sidon, killing one person, on the eve of a withdrawal deadline under a fragile ceasefire between Israel and Hezbollah.

A Lebanese security source said the strike killed a military unit commander from Palestinian Islamist group Hamas, as Israel’s military claimed the raid.

Hezbollah chief Sheikh Naim Qassem said in a televised speech Sunday that Israel "must withdraw from all of the Lebanese territory that it has occupied" on Feb. 18.

The Israeli army said it conducted air strikes in Lebanon on Sunday targeting Hezbollah military sites storing weapons including rocket launchers.

"A short while ago, the IAF (Israeli Air Force) conducted precision, intelligence-based strikes on a number of military sites in Lebanese territory containing rocket launchers and weapons, where Hezbollah activity had been identified," the military said in a statement, without specifying the exact location of the strikes.

Top U.S. diplomat Marco Rubio said on Sunday that the United States and Israel expect the Lebanese state to work towards disarming Iran-backed Hezbollah, which fought a war with Israel last year.

Israeli Prime Minister Benjamin Netanyahu said Sunday that Israel would do what it has to in order to "enforce" the ceasefire with Lebanon.

A woman was killed and several other people wounded Sunday when Israeli forces opened fire on a group of residents attempting to return to the village of Houla in southern Lebanon, the Lebanese state-run news agency reported.

There was no immediate comment from the Israeli military on the incident, which comes two days before the deadline for implementation of a ceasefire agreement that ended the latest war between Israel and Hezbollah in late November, including a full withdrawal of Israeli forces from southern Lebanon.

Senior Hezbollah official Wafiq Safa has denounced Friday's attack on UNIFIL near Beirut's airport during an angry protest by Hezbollah supporters.

Safa said "what happened with UNIFIL... is unacceptable."
