About 7,000 opposition supporters marched through Bucharest on Thursday, while at a separate demonstration later in the day police fired tear gas against protesters who threw bricks and bottles.. Police detained about 100 people.
Interior ministry spokesman Marius Militaru said it was hard to tell for now whether there would be more protests over the weekend. "All I can tell you is that we will line up riot police for public order on the downtown streets."
The demonstrations began after President Traian Basescu criticised the popular deputy health minister who resigned. The minister, Raed Arafat, has since been reinstated in a failed attempt to calm the situation.
