Ukraine's three previous post-Soviet presidents have given their support to mass anti-government protesters.

In a statement, Leonid Kravchuk, Leonid Kuchma and Viktor Yushchenko expressed "solidarity" with peaceful rallies.

Thousands of protesters remain camped in Kiev's Independence Square, and are continuing to block the main government's building.
