The al-Qaida-affiliated al-Nusra Front released on Saturday the video of the execution of captive soldier Mohammed Hamiyeh after conflicting reports had emerged over his death.

The video showed Hamiyeh being executed by a shot to the head, reported Turkey's Anatolia news agency.

Efforts are underway between officials from the rival March 8 and 14 camps in order to hold a legislative session next week to tackle pending issues, reported the daily An Nahar on Saturday.

The efforts are focusing on means to resolve the dispute over the new wage scale, as well as issuing Eurobonds and tackling budget-related affairs.

Prime Minister Tammam Salam is expected to urge on Saturday the United Nations Security Council to meet to tackle the latest developments in the northeastern border town of Arsal, reported An Nahar daily.

It said that he was prompted to take the decision in light of the attack against the army in the area on Friday and the escalation of attacks by gunmen in the outskirts of the town.

Minister of Social Affairs Rashid Derbas voiced apprehension on Saturday that international aid to Syrian refugees in Lebanon could dwindle down further after reports showed that it did, an Nahar daily reported.

“International aid to Syrian refugees has dwindled from 53% in 2013 to 40% at present. I fear that it could decrease further,” dreaded Derbas.

Three rockets landed Friday in the northern Bekaa region after being fired from the Eastern Mountain Range, which straddles both sides of the Lebanese-Syrian border.

“One of the rockets exploded over a secondary school in (the town of) al-Labweh as the other fell below the international highway that links northern Bekaa to Baalbek,” state-run National News Agency said.

The Qaida-linked al-Nusra Front on Friday said it executed captive Lebanese soldier Mohammed Hamiyeh, describing him as the “victim of the Lebanese army's intransigence.”

Turkey's state-run Anatolia news agency said it received a phone call from a Nusra leader in Syria's Qalamun, who confirmed that the group murdered Hamiyeh with several bullets.

An army checkpoint was attacked by a hand grenade on Friday in Tripoli, only hours after a roadside bomb targeted an army vehicle and killed two troops in the Bekaa border town of Arsal.

"An unknown assailant riding a motorbike hurled a hand grenade towards an army checkpoint in the al-Omari area in Tripoli's Syria Street,” state-run National News Agency reported.

U.S. Ambassador to Lebanon David Hale hailed on Friday the unity and cooperation between Lebanese security agencies, saying it would thwart any attempt to cause division.

“The Internal Security Forces, along with the Army, and General Security, have demonstrated bravery and courage in their mission to protect Lebanon’s security and stability,” Hale said during a ceremony to deliver 38 vehicles to the ISF at the ISF Mobile Barracks in Dbayeh.

Two soldiers were killed and three others wounded on Friday after their vehicle was targeted by a roadside bomb in the northeastern border town of Arsal, announced the military in a statement.

The army soon cordoned off the area while a military expert arrived at the scene.

The army has arrested three Syrians, one of whom admitted to witnessing the beheading of a Lebanese soldier taken captive by jihadists in the northeastern border town of Arsal.

The three Syrians, who had infiltrated Lebanon, were arrested in the Baalbek town of Iaat three days ago.
