At least six people have been killed and dozens wounded in five days of continuous clashes in the Ain el-Helweh Palestinian refugee camp in southern Lebanon, first responders said Monday.

Violence broke out late Thursday in the camp, just weeks after similar clashes pitted members of Palestinian President Mahmoud Abbas' Fatah movement against Islamist militants.

The Lebanese Forces has informed French envoy Jean-Yves Le Drian that it will not attend any dialogue conference prior to the election of a new president, LF lawmaker Ghada Ayoub said.

“The Strong Republic bloc’s specifications for the president and his missions are clear and in line with the Doha meeting’s closing statement,” Ayoub said in an interview on Radio Free Lebanon.

The U.N. human rights chief decried Monday the lack of accountability for the 2020 Beirut port blast, urging an international probe into the massive explosion that killed that killed more than 220 people, wounded 7,500 and destroyed swathes of the city.

"Three years after the Beirut explosion, ... there has been no accountability," Volker Turk told the United Nations Human Rights Council, adding "it may therefore be time to consider an international fact-finding mission to look into human rights violations related to this tragedy."

Cabinet failed to convene Monday at the Grand serail to discuss the Syrian refugee crisis amid a new wave of illegal crossings, due to a lack of quorum.

Caretaker Prime Minister Najib Mikati called instead for a consultative ministerial meeting at his office.

The U.N. agency for Palestinian refugees, UNRWA, has opened shelters in schools and other facilities to accommodate over 750 displaced people as fighting and heavy destruction of homes and facilities continued across southern Lebanon's Ain el-Hilweh refugee camp.

"UNRWA, with partners, is responding to the urgent humanitarian needs," said Dorothée Klaus, the director of UNRWA affairs in Lebanon.

Islamist factions in Lebanon's largest Palestinian refugee camp have said they will abide by a cease-fire after three days of clashes killed at least five people and left hundreds of families displaced.

Fighting between Palestinian President Mahmoud Abbas' Fatah movement and Islamist groups has rocked southern Lebanon's Ain el-Hilweh refugee camp since Friday. Fatah and other factions in the camp had intended to crack down on suspects accused of killing one of their military generals in late July.

Three fighters and a civilian have been killed in clashes over the past hours in the Ain el-Helweh Palestinian refugee camp near Sidon, official media reported, as caretaker Prime Minister Najib Mikati rebuked Palestinian President Mahmoud Abbas over the spiralling violence.

The undeclared meeting between Army chief General Joseph Aoun and Hezbollah’s top lawmaker Mohammed Raad tackled the security situations, the Kahale incident and the UNIFIL resolution as well as the presidential file, media reports said.

According to ad-Diyar newspaper, Aoun told Raad that he is not currently engaged in the presidential battle, but is willing to assume the post if there is “national consensus” over his nomination.

Two people were killed Saturday in clashes that erupted again after a relatively calm night at the Palestinian refugee camp of Ain el-Helweh on Sidon's outskirts, official media reported.

Fresh violence broke out late Thursday in Ain el-Helweh, just weeks after deadly clashes pitted members of Palestinian President Mahmoud Abbas' Fatah movement against Islamist militants.

The five-nation committee on Lebanon is inclined to endorse the presidential nomination of Army chief General Joseph Aoun and Qatar will seek to convince Iran of him due to the good relations between the two countries, a media report said on Saturday.
