Caretaker Prime Minister Saad Hariri lamented “obstructions” hindering the government formation while the crisis-hit country seems heading towards an “unknown” future.

Caretaker Prime Minister Saad Hariri on Sunday called on the parties forming the new cabinet to speed up the process in order to "calm the popular storm," as he urged protesters hailing from Tripoli and the North to shun violence and preserve "Beirut's dignity."

“We feared for Beirut yesterday, but as usual, it has stitched the wounds of its sons from the ranks of the security forces and protesters and removed from its face the remains of anger, rioting and the smoke of blazes,” Hariri tweeted, referring to Saturday’s fierce clashes in Beirut between protesters and security forces.

Human Rights Watch has described the Internal Security Forces’ response to the central Beirut demo which turned violent on Saturday as "brutal," calling for an urgent end to what it called a "culture of impunity" for police abuse.

Lebanese Army Commander Gen. Joseph Aoun stressed on Saturday that the Lebanese Armed Forces will not slack-off despite criticisms directed at the military institution.
