Fighting between Hizbullah and a former al-Qaida affiliate on the Syria-Lebanon border halted Thursday after a ceasefire was reached, Lebanese media and Hizbullah outlets reported.

U.S. Ambassador to the United Nations Nikki Haley has urged the U.N. Security Council to consider Hizbullah "a destructive terrorist force" and "a major obstacle to peace" that is "dedicated to the destruction of Israel."

She said the council must get serious about enforcing its resolutions that involve Hizbullah and its backer Iran, including many calling on the armed group to disarm.

Hizbullah fired rockets and artillery Wednesday afternoon at al-Nusra Front's posts in Arsal's Wadi Hmayyed area and blew up Nusra “operations rooms” in the town's outskirts, following cautious calm in the morning.

Prime Minister Saad Hariri stressed that the government’s main goal is to strengthen the State's institution and its military and security forces in order to extend their control over the entire Lebanese territory.

The United Nations Special Coordinator for Lebanon, Sigrid Kaag and the Director of UNRWA in Lebanon, Claudio Cordone, visited the Palestine refugee camp of Ain el-Hilweh, UNRWA said in a statement on Wednesday.

They met on Tuesday with representatives and residents of the camp, including women and youth groups, and visited UNRWA installations and other areas in the camp.

The “second phase” of Hizbullah's offensive against al-Nusra Front militants in the outskirts of Arsal will probably “end at dawn on Sunday,” paving way for the “third phase which opens channels of negotiations to secure the withdrawal of insurgents into Syria,” al-Joumhouria daily reported on Wednesday.

U.S. President Donald Trump called Hizbullah a threat to Lebanon and the entire Middle East on Tuesday, accusing it and Iran of fueling a humanitarian disaster in Syria.

The Lebanese authorities must “disclose the full findings of their investigation” into the deaths of four Syrian detainees, Amnesty International said Tuesday, after the country’s military prosecutor revealed Monday that a forensic report concluded that they had died of “natural causes.”

The Internal Security Forces arrested during search raids in Beirut and the Bekaa valley, a five-member cell involved with the Islamic State terror group, the ISF said in a statement on Tuesday.

Hizbullah fighters have made “additional gains” in their fight against al-Nusra Front militant group along the eastern border with war-ravaged Syria, and plan to wage an assault against the Islamic State organization located on the other side of the outskirts, media reports said on Tuesday.

LBCI said that Hizbullah was able to seize control on Tuesday of Wadi Kamil, Wadi Hammoudi, Makaabat al-Forn, al-Baydar, Shaabat al-Nahle and Wadi Dalil al-Barak, in Arsal's outskirts.
