In an extraordinary sight only one day after police violently dispersed demonstrators in Macedonia with water cannons, smoke bombs and batons, a group of women out to protest formed a human shield around officers to protect them from provocateurs throwing glass bottles.

The women in Skopje, Macedonia’s capital city, were participating in a second day of protests demanding justice after leaked recordings seemed to show officials tried to cover up the 2011 murder of Martin Neshkovski at the hands of a police officer.
