Protesters vowed to carry out disruptive demonstrations Monday in Chicago, a day after baton-wielding police clashed with demonstrators in a violent confrontation that left dozens injured just blocks from where NATO leaders were gathered.
Security was expected to be tight on the final day of the two-day NATO summit, which has played out against a backdrop of protests that has seen thousands taken to the street to protest everything from the war in Afghanistan to the economy.
Occupy Chicago, one of the groups that helped organize the demonstrations, took to social media to urge people to join in another planned demonstration at 10 a.m. ET on Monday.
Dozens were injured in a melee Sunday that came at the end of a largely, peaceful demonstration that began in Chicago's Grant Park, where President Barack Obama delivered his presidential acceptance speech in 2008.
