BEIRUT (AP) — Hundreds of Lebanese protesters have set up tents, blocking traffic in main thoroughfares and sleeping in public squares to enforce a civil disobedience campaign and keep up the pressure on the government to step down.

Banks, universities and schools remained closed on Friday, the ninth day of nationwide protests.

Protesters briefly closed the highway linking the southern city of Sidon to Beirut, burning tires and blocking traffic. The army later removed the tires and reopened the road.

Protesters set up tents on the main highway linking eastern and western Beirut, allowing through only ambulances and army vehicles.

Despite government promises of reforms, the leaderless protesters have dug in, saying the country's incumbent officials are corrupt and must go.

The unprecedented mass protests come amid a deepening economic crisis in Lebanon.
