AP Explains: Iran gas price protests quickly turn violent

Protests over gasoline prices have swept across some 100 cities and towns in Iran, turning violent faster than widespread economic protests in 2017 and rallies over the country’s disputed 2009 presidential election. Prior to that, online videos purported to show people abandoning their cars on major highways and marching on city centers. Demonstrations devolved into violence as rioters set fire to gas stations, attacked banks and robbed stores.
