Several dozen supporters of Georgia’s ex-president Zviad Gamsakhurdia have thrown eggs at a car in which visiting U.S. businessman and philanthropist, Hungarian-born billionaire George Soros was traveling, Interfax news agency reported.

The incident took place on Monday after Soros walked out of the Marriott hotel in downtown Tbilisi and got into his car. Gamsakhurdia’s supporters, who were chanting slogans criticizing Soros, began throwing eggs at the departing car.

The protestors accused Soros of involvement in the “Rose revolution” in 2003, which helped Georgia’s current authorities, including the President Mikhail Saakashvili, come to power. They promised to hold more actions.

Soros, who arrived in Tbilisi on Saturday, is meeting Saakashvili at the moment.

Before the beginning of his visit Georgian opposition Labor Party Leader Shalva Natelashvili said his supporters had prepared a “surprise” for Soros, more “civilized”, “refined”, “unexpected, but quite unpleasant”, than “throwing eggs”.

The Laborites, however, have not kept their promise yet.

Soros, the head of the Development Foundation in his name, has been actively supporting democratic movements in Eastern Europe and his foundation has succeeded in precipitating changes in Serbia, Georgia and Ukraine. Several post-Soviet states have even declared him persona non grata.
