Tens of thousands march in Belgrade after mass shootings

Marchers in Serbian capital's second protest in a week decried populist president Aleksandar Vui

Tens of thousands of people have marched through Belgrade, blocking a key bridge in the second large protest since two mass shootings that rattled Serbia and left 17 people dead, including many children.

Protesters gathered in front of the parliament building on Friday before filing by the government's HQ and on to a highway bridge spanning the Sava River, where evening commuters had to turn their vehicles around to avoid getting stuck. At the head of the column was a black banner reading Serbia against violence."
