On Thursday, protests in Greece only continued to intensify as journalists joined in. Tear gas was fired and farmers fought with riot police, although no injuries were reported. It is estimated that 5,000 farmers participated in the strike using tractors to block the entrance to the agricultural fair that was scheduled to happen in the city center of Thessaloniki. This strike is over the potential income losses that could occur from tax and pension reforms.
