Protests demanding the removal of politicians deemed incompetent and corrupt have gripped Lebanon since October 17 and forced the resignation of the government.
Hundreds of people hit the streets of the Lebanese capital on Saturday to mark 100 days of anti-government demonstrations and denounce a new cabinet line-up.
A new cabinet was announced on Tuesday after a three-month vacuum.
But protesters say the ministers were chosen along sectarian lines and that the line-up does not satisfy their demands for a government of independents and technocrats.
On Saturday, several marches were held in Beirut under the slogan "No trust", with protesters converging on the city centre.
Demonstrators chanted "Revolution, Revolution" under the watchful gaze of security forces, who were deployed in high numbers.
The protest movement has largely been peaceful since it began more than three months ago but has turned violent in recent weeks.
"The government (formed on Tuesday) is not the one we have been seeking," demonstrator Perla Maalouli said in central Beirut.
"We demand a salvation government... not one whose members are selected according to (sectarian) quotas", which the protest movement had mobilised against, she said.
Apportioning positions between Lebanon's main Christian, Sunni and Shia communities has been key to forming governments since the end of the 1975-1990 civil war.
Maalouli said politicians had failed to heed the protest campaign.
"After 100 days (of demonstrations), they continue to do as they please, as if the people have not spoken," she said.
The new government, headed by academic Hassan Diab, faces huge economic and political challenges.
Lebanon has one of the world's highest debt-to-GDP ratios and economists have argued it is hard to see how the near-bankrupt country could repay its creditors.
The Lebanese pound has lost over a third of its value against the dollar in the parallel market and banks are tightening restrictions on dollar transactions amid a liquidity crunch.
The economic downturn has raised questions over whether Lebanon will turn to the International Monetary Fund for a bailout, an option the government has yet to comment on, but which some officials regard as inevitable.
Earlier on Saturday, the new Finance Minister Ghazi Wazni met with a senior IMF official in Beirut, a day after holding talks with a World Bank delegation.
The new premier Diab on Wednesday warned that Lebanon faces an economic "catastrophe", but has pledged that his government will strive to meet the protesters' demands.
