Protests continued in Athens just hours after a police van was hit by gunfire. Thousands of people marched through the city in a demonstration that was largely peaceful. In the earlier incident, shots were fired at a police van when it stopped at traffic lights outside a university campus in eastern Athens. Two bullets hit the van, bursting a tyre, but no-one was injured.The university has become the centre of anti-government protests in Greece that have now run into a third week. The fatal shooting of a teenager at the beginning of December unleashed widespread unrest. Many protestors are angry at high youth unemployment, government scandals, and unpopular economic reforms.
