Security forces deployed "heavily" in the northern town of Halba near several banks and government institutions, the state-run National News Agency reported on Tuesday.

The Lebanese army said it had arrested dozens of suspects for "vandalism", after days of protests triggered by a plunging local currency amid the worst economic crisis in decades.

Prime Minister Hassan Diab on Monday declared “war on corruption” during a meeting with the country’s supervisory bodies.

“Today the whole world is asking Lebanon to combat corruption as a precondition for helping us. In the current situation, we are accused that we have not achieved anything, but this issue has become on the table and it has become the government’s top priority,” Diab said.

President Michel Aoun on Monday stressed the need for “preemptive operations to arrest plotters and instigators of acts of vandalization to curb them and prevent their recurrence,” following days of violent protests in Beirut and Tripoli.

“The acts of sabotage that occurred recently, some of which took a sectarian turn, in addition to the systematic attacks on security and military forces, are no longer acceptable and can lead to dangerous ramifications,” Aoun warned during a Higher Defense Council meeting in Baabda.

President Michel Aoun on Monday convened the country's Higher Defense Council after days of angry protests over a deepening economic crisis.

The United Nations on Monday denied reports referring to possible U.N. withdrawal from Lebanon, stressing that it is not planning to "stop its operations" or "evacuate its staff" from the country.

"In response to speculative stories referring to possible U.N. withdrawal from Lebanon in some media outlets in the past days, the United Nations considers it necessary to deny such unsubstantiated speculations," the U.N. said in an English-language statement.

Prime Minister Hassan Diab on Monday underscored that “thugs belong in jail,” referring to those who carried out acts of rioting in Beirut and Tripoli over the past days.

Diab was speaking during a financial-security meeting that he chaired at the Grand Serail to “follow up on the current security situations and control the U.S. dollar exchange rate,” the National News Agency said.

Interior Minister Mohammed Fahmi on Sunday issued a memo ending the odd-even rule for the movement of vehicles, which has been in place since April 7 as part of the so-called state of general mobilization over the coronavirus pandemic.

The rule had rationed the movement of vehicles with those whose license plates end in an odd digit allowed on the streets for three days a week and those whose plates end in an even digit allowed to move for the three other days. The system had barred both categories of vehicles from moving on Sundays.

Lebanon confirmed only four COVID-19 coronavirus cases over the past 24 hours, a drop from twenty daily cases recorded on Saturday.

A statement issued by the Health Ministry said two of the infected individuals are residents and the other two are repatriated expats. It said the two local cases have been traced to known sources.

Lebanese Forces leader Samir Geagea on Sunday accused the government of negligence towards the rioting that central Beirut had witnessed in recent days.

“As much as we as Lebanese cling to freedom of opinion and expression, we also cling to public order, public safety and the preservation of public and private property,” Geagea said in a tweet.
