U.S. Ambassador David Hale said Tuesday that Lebanon should be “insulated” from the region's conflicts and reiterated Washington's commitment to build the capabilities of the Lebanese army and police.

Hale said he reiterated to Prime Minister Tammam Salam U.S. support for the Lebanese army and all Lebanese security services in “their work to secure” Lebanon’s borders, protect it from terrorism and “insulate” the country from regional conflicts through its dissociation policy.

Lebanese Forces chief Samir Geagea warned on Tuesday that the clashes between the army and terrorists in the northeastern border town of Arsal could spread to other areas in Lebanon.

In a speech at the emigrants annual meeting in Maarab, Geagea said: “The security situation in Arsal is very dangerous even if it is isolated.”

Army chief General Jean Qahwaji urged France on Tuesday to speed up the delivery of weapons under a Saudi-financed deal, as his troops battle jihadists on the Syrian border.

"This battle requires equipment, materiel and technology that the army doesn't have," Qahwaji told Agence France Presse.

Al-Mustaqbal Movement leader Saad Hariri reiterated staunch support to the Lebanese army in its battle against terrorism, rejecting attempts to cover up for Hizbullah's engagement in the fight raging in neighboring country Syria.

“Our support to the army against gunmen who infiltrated (the northeastern border town of) Arsal is steadfast that will not undergo political bids,” Hariri said in a statement issued by his press office on Tuesday.

Clashes between the Lebanese army and gunmen left a child dead and several injured on Tuesday as roads in and around the northern city of Tripoli remained blocked, the state-run National News Agency reported.

The fighting renewed on Tuesday morning after a cautious calm following a night of gunbattles between the army and masked men.

Abou al-Hassan al-Filastini, the emir of the Islamic State of Iraq and the Levant (ISIL), who initiated the attack on the northeastern town of Arsal on Saturday, was killed.

According to As Safir newspaper published on Tuesday, al-Filastini succumbed to wounds he sustained during battles with the Syrian army in the Qalamoun, which borders the Bekaa valley town of Arsal.

Hizbullah Secretary-General Sayyed Hassan Nasrallah has reportedly advised Progressive Socialist Party leader Walid Jumblat to visit Free Patriotic Movement chief Michel Aoun to resolve the presidential deadlock.

“We have a president … He is Aoun and we continue to back him,” As Safir daily quoted Nasrallah as telling Jumblat.

The U.N. Security Council on Monday condemned attacks by extremist groups in Lebanon, backing the government's military response but warning Beirut against being dragged deeper into the Syria conflict.

Scores of Lebanese soldiers have been killed and injured in three days of clashes with jihadists in the northeastern town of Arsal near the Syrian border, according to the Lebanese army.

A rocket was fired from southern Lebanon on Monday towards Israel, but missed its target and hit Lebanese territory instead.

"A rocket was fired a while ago from a region between al-Jormoq and al-Zafata (in the South),” the state-run National News Agency reported on Monday evening.

Several people rallied on Monday in the Bab al-Tabbaneh neighborhood of the northern city of Tripoli to protest what they considered the “army and Hizbullah's shelling” of the eastern border region of Arsal.

The protesters' march took off near Tripoli's Harba mosque and they roamed streets surrounding Bab al-Tabbaneh, arriving at the northern city's Abou Ali roundabout, the state-run National News Agency reported.
