A Policeman walks through Carnival revellers during the annual Rose Monday parade on February 8, 2016 in Cologne, Germany. The centuries-old tradition of German carnival occurs in February and runs until Ash Wednesday, the start of Lent, and culminates in Rose Monday celebrations. Police are on added alert this year, particularly in Cologne, due to the New Year`s Eve sex attacks on women that have been attributed to gangs of migrants.
