Iran Press/ Middle East: More than 120 of those were treated in hospitals as well as security force members. The Internal Security Forces said 142 of its members were injured, including 7 officers, some with serious concussions.
It was the worst violence since the unrest erupted three months ago, the official National News Agency reported.
Security forces were bracing for more rioting by reinforcing concrete barriers and stringing coils of razor wire across downtown Beirut.
The public prosecutor said all those detained during the previous night's riots would be released except those with other pending cases.
The clashes took place amid a rapidly worsening financial crisis and an ongoing impasse over the formation of a new government. The cabinet headed by Prime Minister Saad Hariri resigned in late October.
Security forces and the military were girding themselves for more violence, following protester calls for more rallies on Sunday.
Riot police had fired volleys of tear gas and rubber bullets late into the night Saturday to disperse the thousands of demonstrators. The protesters, who came from the country's north, east and the capital itself, clubbed security forces with tree branches and metal bars and fired flares and fireworks while lobbing stones and other projectiles at them.
Caretaker Interior Minister Raya al-Hassan said that security forces were ordered to protect peaceful protests.
"But for the protests to turn into a blatant attack on the security forces, public and private properties, this is condemned and totally unacceptable," she tweeted Saturday.
The protesters have been rallying against the country's political elite who have ruled Lebanon since the end of the 1975-90 civil war.
They blame politicians for widespread corruption and mismanagement in a country that has accumulated one of the largest debt ratios in the world.
