Serbians paraded life-size figures of leading government figures in prison jumpsuits on Saturday during a seventh week of protests since two mass shootings triggered nationwide protests. In the capital Belgrade, tens of thousands of demonstrators blocked a major highway and demanded that government heads roll for permitting a culture of violence they said was to blame for the killings of 18 people on May 3 and May 4. "Vucic out!" chanted the crowd in Belgrade, referring to Serbian President Aleksandar Vucic, as his likeness was paraded alongside that of Prime Minister Ana Brnabic and other prominent figures in black-and-white jail garb.
