Hundreds of anti-government protesters blocked roads in Beirut and in other parts of Lebanon, in a bid to press for political change.
A semblance of normality had gradually returned to the country last week after Saad al-Hariri resigned as prime minister.
While banks reopened for the first time in two weeks, schools continued to remain closed.
Hariri continues in a caretaker capacity until a new government is formed.
The nationwide protests were triggered on October 17 after the government announced its decision to tax WhatsApp messages.
