A demonstrator is detained by riot police officers during a protest against a new law proposed by the government, which toughens penalties on any type of protest and public disorder without prior permission of local authorities in Valparaiso city, about 121 km northwest of Santiago, July 25, 2012.
At least one protester was detained by police outside the Colorado Convention Center in downtown Denver just after noon on Monday, as the Democratic National Convention was getting underway.
