Millions of workers are on strike all across Europe. Violence in some areas as police and protesters clashed. Demonstrators are rallying against spending cuts they say have made the economic crisis there worse. Hundreds of flights were canceled and trains barely ran in Spain and Portugal where unions held their first ever coordinated general strike. The biggest protests are happening in Spain, Greece, Portugal and Italy - the countries that have faced some of the deepest tax increases and cutbacks in the Eurozone crisis.
