Protesters closed major roads leading to the Lebanese capital, causing traffic jams and triggering a call by the head of the hospitals union who warned that such moves are preventing oxygen supplies from reaching medical centers treating patients.
Demonstrators burnt tyres to block main roads all over Lebanon for the seventh straight day in anger at more than a year of economic crisis and seven months of political paralysis.
"We have said several times that there will be an escalation because the state isn't doing anything," said Pascale Nohra, a protester in Jal al-Dib."
Protests at the start of Lebanon's financial crisis in 2019 brought hundreds of thousands onto the streets to bring down the government.
On Monday, three main roads leading south into the capital from Zouk, Jal al-Dib and al-Dawra were blocked while, in Beirut itself, protesters briefly blocked a main road in front of the central bank.
In Tyre, one man tried to burn himself by pouring gasoline on his body but civil defence stopped him in time, the state news agency said.
Tens of thousands of jobs have been lost in the crisis, bank accounts have been frozen and many have started to go hungry.
After an explosion devastated whole tracts of Beirut in August, the next government resigned.
But the new prime minister-designate, Saad al-Hariri, is at loggerheads with President Michel Aoun and has been unable to form a new government to carry out the reforms that would unlock billions of dollars of international aid.
Since the Lebanese pound tumbled to a new low last Tuesday, protesters have been blocking roads daily.
On Saturday, caretaker prime minister Hassan Diab threatened to quit to raise the pressure on those blocking the formation of a new government.
Diab is meeting with President Aoun, several caretaker ministers, the central bank chief and financial and security officials on Monday, the state news agency said.
Maronite Patriarch Bechara Boutros al-Rai hit out at the politicians in his Sunday sermon:
"How can the people not revolt when the price of one dollar has surpassed 10,000 Lebanese pounds in one day, how can they not revolt when the minimum wage is $70?"
Rai has called for an UN-sponsored international conference to help Lebanon.
