A pro-choice protest in Sioux Falls, South Dakota Wednesday escalated as several hundred demonstrators marched down a street, blocking traffic and police deployed smoke and declared an "unlawful assembly," according to reports. 

The protest, which police said wasn’t permitted, started in downtown Sioux Falls around 7 p.m., according to Dakota News Now. 

A "couple" of protesters were arrested for failing to disperse or other misdemeanors, Sioux Falls Police Chief Jon Thum said, according to the Sioux Falls Argus Leader. It was unclear exactly how many protesters were arrested.  

The unlawful assembly was declared after 9 p.m.
