COLOGNE, Germany, Jan 9 (Reuters) - German riot police fired water canon to disperse a demonstration by the anti-Islam PEGIDA movement in Cologne after protesters threw fire crackers and beer bottles at officers, according to a Reuters witness.
Two people were injured in the clash. The riot police made a number of arrests.
Police had called on demonstrators, some of whom had chanted "Merkel must go", to return to a square near the city's train station, from where they had set out on a march through Cologne.
When they continued to throw fire crackers and bottles, police used two water canons to disperse the group. (Reporting By Joseph Nasr; writing by John O'Donnell; Editing by Toby Chopra)
