Lebanon's judiciary has charged two anti-Hezbollah activists in absentia with inciting Israeli attacks against the Iran-backed group and sentenced them to 15 years in prison, a judicial official told AFP on Friday.

It is the harshest sentence yet against activists expressing support for Israel, which has officially been at war with Lebanon for decades.

Parliament Speaker and Hezbollah ally Nabih Berri said Friday that the Iran-backed group would withdraw from the area south of Lebanon's Litani River if Israel pulls out and a comprehensive ceasefire is reached.

"I agree to... Hezbollah's withdrawal from south of the Litani River in parallel with an Israeli withdrawal from the areas it occupies" and "a complete and comprehensive ceasefire without conditions", Berri, who acts as Hezbollah's mediator, said in a statement, as he blasted the rest of the agreement text as too "unjust" and "unworthy of discussion."

Israeli ministers voiced strong opposition to a proposed ceasefire with Lebanon during a security cabinet meeting, though no official vote was held.

The pause came after Hezbollah leader Sheikh Naim Qassem rejected the U.S.-backed proposal, demanding instead a "comprehensive" ceasefire and the complete withdrawal of Israeli forces from southern Lebanon.

The U.N. on Friday more than doubled its aid appeal for Lebanon as the country reels from Israel's war against Iran-backed Hezbollah, saying nearly $640 million was needed over six months.

"The humanitarian crisis in Lebanon is severe and deteriorating," the U.N. humanitarian agency OCHA said in a revised appeal for the country.

Israeli strikes overnight in the south Lebanon city of Tyre killed seven people, a source from Lebanon's civil defense told AFP on Friday, despite a ceasefire in the Israel-Hezbollah war.

One strike near the Jabal Amel hospital killed four people, wounded seven and lightly damaged the facility, while another elsewhere in the city killed three and wounded five, including two children.

The Israeli military said on Thursday that one of its soldiers was killed in southern Lebanon, the first fatality since the announcement of a new ceasefire plan.

Captain Eitan Shmuel Lemberg, 21, "fell in combat" the military said in a brief statement. A military source told AFP that he was killed by a missile fired by Hezbollah at an Israeli tank.

Israeli strikes on south Lebanon and West Bekaa killed eight people and wounded 15 others on Thursday, hours after a new ceasefire was announced between Lebanon and Israel, the Health Ministry said.

An Israeli strike in on Sohmor in West Bekaa killed five people, while another attack near the southern city of Tyre killed three more, the ministry said.

Free Patriotic Movement chief Jebran Bassil on Thursday criticized both the Lebanese state led by President Joseph Aoun and PM Nawaf Salam, and his former ally Hezbollah.

"True peace is not merely the absence of tension, but the achievement of justice. This is a phrase coined by Martin Luther King Jr. and ignored by many, especially those who believe in imposing peace by force," Bassil said.

U.N. Secretary-General Antonio Guterres condemned the latest killing of a peacekeeper in southern Lebanon and demanded those responsible be brought to justice, his spokesman said Thursday.

The Swiss subsidiary of British bank HSBC has been charged in France as part of an embezzlement probe into former Lebanese central bank chief Riad Salameh, the financial crimes prosecutor's office said Thursday.
