~ Demonstrators gather at the prime minister's offices in Beirut ~
Hundreds of thousands of supporters of Hezbollah and its pro-Syrian allies have held a mass rally in Beirut to protest against Lebanon's government.
As night fell, several thousand set up tents outside PM Fouad Siniora's office for an open-ended sit-in.
The opposition says it will keep up the pressure until the government resigns.
The protest follows weeks of rising tension in Lebanon, with the killing of a leading anti-Syrian politician and resignations from the cabinet.

Police estimated its size at 800,000 people, but Hezbollah claimed it was larger, the Associated Press news agency said.
