President Joseph Aoun on Monday accused Hezbollah of working towards the "collapse" of the state, after the pro-Iran group launched an attack on Israel, expressing Beirut's readiness for "direct negotiations" with Israel.

Begun after Hezbollah launched rockets towards Israel a week ago, Israel's bombing campaign has killed at least 394 people and displaced more than half a million.

Hezbollah on Monday welcomed the selection of Mojtaba Khamenei as Iran's new supreme leader, pledging allegiance after his predecessor and father Ali Khamenei was killed in U.S.-Israeli attacks.

"We in Hezbollah extend our warmest congratulations and blessings on this occasion. We renew our pledge of loyalty to this blessed approach and our steadfastness on the path of allegiance," the group said in a statement.

The military court in Beirut ordered three Hezbollah members released on a $20 bail each, judicial officials said Monday.

The Lebanese government last week declared Hezbollah’s military activities illegal and ordered the country’s security forces to detain those who were behind the strikes on Israel.

At least twenty people were killed in Israeli strikes on south Lebanon and Beirut's southern suburbs on Monday.

Sixteen people were killed and 40 wounded in strikes on Tayrdebba and Jwayya in south Lebanon, the health ministry said, while Israeli airstrikes on al-Qard al-Hassan branches in Dahieh killed one person and wounded 12 others.

French President Emmanuel Macron arrived in Cyprus on Monday to discuss regional security, while Paris deployed warships to the Mediterranean and the U.S.-Israeli war on Iran stretched into a second week.

United Nations Special Coordinator for Lebanon Jeanine Hennis-Plasschaert began Monday an official visit to Israel.

In southern Lebanon, the Israeli military said it launched a "targeted and limited raid" to "locate and eliminate" Hezbollah operatives and infrastructure using a brigade combat team under the command of the 36th Division.

The military said before they initiated the operation, its forces launched a combined air and ground attack in the area.

Parliament on Monday postponed legislative elections, initially due to be held in May, by two years, according to a statement from the parliament speaker, due to the war between Israel and Iran-backed group Hezbollah.

MPs convened on Monday including Mohammad Raad, head of Hezbollah's parliamentary bloc, even as Israeli warplanes flew above the nearby southern suburbs of Beirut.

The Israeli army started a new wave of strikes on Dahieh on Monday, after it warned it would target branches of Al-Qard al-Hassan, a financial firm linked to Hezbollah.

Two Israeli airstrikes targeted a branch of Al-Qard al-Hassan in Sfeir in Beirut's southern suburbs. Other strikes targeted branches of the firm in other areas including Haret Hreik, Beer al-Abed, and Burj al-Barajneh.

The human rights group Human Rights Watch said in a report Monday that the Israeli military "unlawfully" hit a village in southern Lebanon with shells containing white phosphorus, a controversial incendiary munition.

Through geolocating and verifying seven images, Human Rights Watch said Israel fired white phosphorus using artillery at residential areas in the southern Lebanese village of Yohmor. It happened hours after the Israeli military warned the residents of the village and dozens of others in southern Lebanon to evacuate.
