KYIV (QHA) - Ukraine's three previous post-Soviet presidents have given their support to mass anti-government protesters, BBC reports. In a statement, Leonid Kravchuk, Leonid Kuchma and Viktor Yushchenko expressed "solidarity" with peaceful rallies. "We express solidarity with the peaceful civic actions of hundreds of thousands of young Ukrainians," said a statement from Leonid Kravchuk, Leonid Kuchma and Viktor Yushchenko, posted on Yushchenko's party website. "For the first time, the Ukrainian people have come out on the streets with an apolitical demand that has unprecedented mass support," reads the statement. Thousands of protesters remain camped in Kiev's Independence Square, and are continuing to block the main government's building. They are angry at the government's last-minute decision not to sign an association deal with the EU. German Foreign Minister Guido Westerwelle on Wednesday visited protesters on Independence Square, saying that "the gates of the European Union are still open". Meanwhile, Russia - which wants Kiev to join the Moscow-led Customs Union - has urged the West not to interfere in Ukraine.
