The Israeli army is readying for several scenarios on the northern front with Lebanon, Israel’s Maariv newspaper said.

“Israeli intelligence has detected increased Hezbollah activity in various Lebanese regions, including North Litani, the Bekaa and south Beirut,” the Israeli daily added.

An Israeli drone strike on Monday targeted a car in the southern town of al-Sharqiyeh in the Nabatiyeh district, killing one person and wounding seven others, the Health Ministry said.

Al-Arabiya’s Al-Hadath channel identified the person targeted as “Hezbollah commander Mohammad Ali Hadid,” saying he had survived a similar drone strike overnight in the Zefta area.

Israeli Prime Minister Benjamin Netanyahu has claimed that Hezbollah is attempting to "rearm" itself.

"We expect the Lebanese government to fulfill its commitment -- to disarm Hezbollah -- but it is clear we will exercise our right of self-defense under the terms of ceasefire," Netanyahu told the Israeli cabinet at its weekly meeting on Sunday.

Hundreds of people gathered in south Lebanon's Nabatiyeh on Sunday to mourn five Hezbollah members killed in recent Israeli attacks, an AFP correspondent said, as Israel warned of intensifying attacks against the Iran-backed group.

On Saturday, an Israeli strike killed four people in Kfar Rumman, Nabatiyeh district, the Lebanese health ministry and the Israeli military said.

There are “serious estimations” that Hezbollah has started to regain its capabilities and has succeeded in smuggling hundreds of short-range missiles from Syria, an Israeli official said on Sunday.

Israel warned Sunday that its military would step up its attacks against Hezbollah in southern Lebanon, a day after the Lebanese health ministry reported four people killed in an Israeli air strike.

U.S. envoy Tom Barrack has called Lebanon "a failed state" in remarks underscoring Washington's frustration with what he called Beirut's "paralyzed government."

Speaking at the Manama Dialogue summit in Bahrain during a panel on "U.S. Policy in the Levant," Barrack pointedly said Lebanon is the only state in the region "not jumping in line" with the new Middle East realignments.

Egyptian intelligence chief Hassan Rashad has carried to Beirut an initiative calling for a three-month ceasefire during which Israel would completely halt attacks and hand over the Lebanese captives in return for “fully ending Hezbollah’s presence south of the Litani River,” al-Liwaa newspaper reported on Saturday.

Hezbollah chief Sheikh Naim Qassem noted Friday that Israeli attacks on Lebanon increase whenever a U.S. official visits the country or talks about it.

“What is America's stance on 5,000 Israeli violations against Lebanon?” Qassem asked, in a televised address.

Lebanon placed its army on high alert Thursday after President Joseph Aoun ordered troops to confront any Israeli incursion into the country’s south, following a deadly overnight Israeli army ground raid in the village of Blida near the border.

According to Lebanese media reports, the army began deploying reinforcements and setting up new positions in southern villages, including in Blida.
