Leipzig police say 69 officers have been injured in clashes with rioting leftwing protesters and that they had to use tear gas and water cannons to disperse the group.

Some 50 police cars were also damaged in the riots Saturday evening, which started after hundreds of leftwing activists demonstrated against a rally by far-right protesters in the eastern German city of Leipzig earlier in the day.

Police said Sunday they temporarily detained 23 people after the leftist rioters threw stones at police, erected street blocks and burned down garbage cans. The protesters also demolished store front windows and two bus stops.

It was not immediately clear how many protesters were injured in the clashes.
