Nineteen demonstrators were taken away by police in Philadelphia and Pittsburgh after marchers blocked streets while advocating for higher wages for fast-food restaurants.
Police arrested 11 in Philadelphia in Thursday's protest that was part of a national campaign planned for about 150 cities. Eight were arrested in Pittsburgh.
In Philadelphia, more than 100 fast-food workers and their supporters trekked about a mile down Broad Street from a cluster of fast-food restaurants in north Philadelphia to a McDonald's in Center City.
Protesters chanted and held signs advocating for a $15-an-hour wage and the right to unionize without retaliation from their employers. In Pittsburgh, nearly 200 protesters marched up Penn Avenue and stopped outside a McDonald's where they chanted "hold your burgers, hold your fries, make my wages super-sized."
