TBILISI, Georgia (AP) - With street protests in Georgia’s capital in their sixth day, opposition leaders called on thousands of demonstrators Tuesday to keep up the pressure until President Mikhail Saakashvili steps down.

An estimated 12,000 protesters jammed the street in front of parliament Tuesday, which has been closed to traffic since the demonstrations began. About a thousand people then set out for an evening protest outside the presidential residence, while several thousand marched to the main public television station to demand more live coverage.

At both locations, some protesters stood in cages they said symbolized that Georgia had turned into a police state under Saakashvili, a U.S.-educated lawyer who came to power five years ago on promises of democratic reforms.
