Tensions are high in Kiev, the capital of Ukraine, as huge crowds of protesters vent their anger at President Viktor Yanukovych. He has rejected a plan to strengthen ties between Ukraine and the European Union. The demonstrators fear that Yanukovych will instead strengthen ties with Russia and some former Soviet republics. There have been angry face-offs between protesters and police. In one incident on Monday, a line of demonstrators pushed right up against the shields of a line of police. Tempers were flaring until a group of parliamentarians walked between the two lines and separated them.
