VIDEO: Officers Injured, Marchers Arrested During Weekend Black Lives Matter Protests

Hundreds of protesters were arrested across the country and law enforcement officers were injured in Saint Paul, MN, and Baton Rouge, LA, Saturday night as demonstrations continued nationwide over police violence.

Around 102 protesters were taken into custody in Saint Paul, while more than 100 people were arrested in Baton Rouge, LA, police in both cities told NBC News .

In St. Paul, protesters blocked Interstate 94 and chanted the name of Philando Castile, a 32-year-old man who was fatally shot by a St. Anthony police officer in Falcon Heights on Wednesday.

Minneapolis Police said on Twitter that people on an overpass were "throwing objects at officers, dumping liquid on officers" and others were throwing rocks and a construction material called rebar. Police also said a molotov cocktail was thrown at officers.

More than 20 officers were injured by the attacks. NBC News reports one officer suffered broken vertebrae after being struck in the head by a piece of concrete dropped from an overpass.

In Atlanta, protesters also tried to block an interstate highway. CNN reported that as many as 2,000 people marched onto a ramp of the Interstate 75/85 connector, where they were met by Georgia State Police.

In Baton Rouge, where hundreds of protesters gathered for demonstrations over the fatal shooting of Alton Sterling, one officer lost teeth when he was struck in the mouth by a thrown object.
