Thousands of protesters are gathering at a Moscow square for a march on the eve of Vladimir Putin’s inauguration as president. The protest has been boldly billed by opposition leaders as the “March of a Million,” but the early turnout indicates the numbers won’t be anywhere close to that. About 5,000 had gathered an hour before the planned start of the Sunday march.(AP Photo/Alexander Zemlianichenko)
