Lebanon needs to quickly form a new government to stop a collapse and worsening economic and security conditions, caretaker prime minister Saad al-Hariri tweeted on Monday. Politicians have failed to agree on a government or an economic rescue plan since protests pushed Hariri to quit as prime minister in October.

Beirut has been rocked in recent days by some of the worst violence since the unrest began, with 370 injured in clashes between protesters and security forces on Saturday, Reuters said.

“Our government resigned in order to transition to a new government dealing with popular changes but obstruction has continued for 90 days and the country is moving toward the unknown,” Hariri said.

Last month, little-known former minister Hassan Diab was designated PM with the backing of the Hezbollah movement and its allies, but a deal on a cabinet has yet to be announced.
