Thousands of people are gathering amid tight security in downtown Beirut, ahead of a major rally to protest government corruption and the country's dysfunctional political system.

At least two or three armored personnel carriers were deployed around the prime minister's office Saturday. A man over a megaphone chanted: "Declare it a revolution!"

Saturday's protest is expected to be the largest of demonstrations that began last week over garbage piling up in the streets of Beirut, following the closure of a main landfill. But the government's failure to resolve the crisis has evolved into wider protests against a political class that has dominated Lebanon since the end of the country's civil war in 1990.
