Human Rights Watch called on Lebanon Tuesday to release a son of Libya's former leader Moammar Gadhafi, saying he had been held on "spurious charges" for eight years.

Lebanon in 2015 arrested and accused Hannibal Gadhafi, known for living the high life, of withholding information about the disappearance of Lebanese Shiite cleric Imam Moussa Sadr in 1978.

EU foreign policy chief Josep Borrell on Tuesday said preventing the spread of the Gaza conflict to Lebanon at all costs should be one of the top priorities in the region.

Israeli warplanes and artillery struck Tuesday the border towns of Wadi Slouki, Houla, Kfarkila, Mays al-Jabal, and al-Abbasiyya in south lebanon.

The Israeli army used phosphorus bombs, and dropped leaflets on Kfarkila warning residents that Hezbollah is launching missiles from the region.

Several Hamas officials who were living in Lebanon have fled to neighboring countries, in the wake of Israel’s assassination of Hamas deputy chief Saleh al-Arouri in Beirut’s southern suburbs, the Israeli Public Broadcasting Corporation has reported.

Lebanese officials discussed five points with U.S. mediator Amos Hochstein during his visit last week to Lebanon, a media report said.

Below are the five points, as published Monday by al-Liwaa newspaper:

Hezbollah targeted Monday gatherings of Israeli troops near the Mattat and the Ramim barracks, surveillance equipment in Metula, and the post of Birkat Risha with Burkan rockets .

Israel shelled the southerns towns of Dhaira, al-Jebbayn, Tayr Harfa, Aita al-Shaab, Hanine, Shihine, al-Hamames hill near al-Khiam, the Marjeyoun plain, and Em el-Tout.

Two "civilians" were killed in northern Israel on Sunday after an anti-tank missile fired from Lebanon hit their home in a town near the border, Israeli rescuers said.

The missile hit a home in the town of Yuval in northern Israel, killing a man in his 40s and his mother, who was in her 70s, the rescuers said. Although Yuval is one of more than 40 towns along the northern border evacuated by the government in October, Israeli media reported that the family stayed in the area because they work in agriculture. Hezbollah meanwhile said that the attack targeted an Israeli military force and inflicted deaths and injuries.

Hezbollah leader Sayyed Hassan Nasrallah stressed Sunday that Hezbollah does not not fear war or U.S. and Israeli threats, while emphasizing that his group will not negotiate over the situation on the border before the end of Israel’s war on Gaza.

“We will continue and our front is inflicting defeats on the enemy,” Nasrallah said in a televised speech commemorating Hezbollah senior military commander Wissam Tawil, who was assassinated by Israel on Monday.

Hezbollah on Sunday appeared to have intensified its attacks on Israeli posts compared to the past few days, hours before a speech by Hezbollah chief Sayyed Hassan Nasrallah marking one week since Israel’s assassination of senior Hezbollah military commander Wissam Tawil.

In a statement, Hezbollah said it attacked an Israeli force in the Kfar Yuval area in northern Israel, causing deaths and injuries.

Israeli soldiers detained two sisters of Saleh al-Arouri, a top leader of Hamas who was killed in Lebanon this month, Palestinian sources and the Israeli army said on Sunday.

The killing of Arouri, the deputy chief of Hamas, in a southern suburb of Beirut on January 2 was widely attributed to an Israeli drone strike, fuelling fears that Israel's war in Gaza could widen into a regional conflict.
