The demonstrations against Prime Minister Fuad Siniora's pro-Western government are being organized by Hizballah and its pro-Syrian allies.
Siniora has vowed that his government will not be toppled by the protests.
Speaking on national television on November 30, Siniora pledged to stand firm against what he called a possible "coup" against Lebanon's democratic system.

Tensions in Lebanon have again been rising since an anti-Syrian government minister was murdered last week, and six pro-Syrian lawmakers quit Siniora's cabinet.
