Lebanon's interior ministry on Sunday ordered troops to "use all necessary means" to prevent demonstrations Monday against Syria's military deployment, but protesters vowed to hold them anyway.
The demonstrations are to center on whether Syria played a role in the assassination of former Lebanese Prime Minister Rafik Hariri in the capital on February 14.
Since then, thousands of demonstrators have peacefully protested Syria's military presence in Lebanon.
Monday's demonstrations were expected to be massive: Lebanon's pro-Syria government faces a possible vote of no confidence Monday. In advance of that parliamentary action, tens of thousands of Lebanese were hoping to take to the streets.
