Serbia’s parliament descended into chaos on Tuesday as opposition lawmakers threw smoke grenades and tear gas inside the chamber to protest against the government and support demonstrating students.

The cleaners had scrubbed the debating chamber clean before MPs arrived for Wednesday's session in Serbia's National Assembly. Spent smoke bombs, smears of egg yolk and a dusting of white fire extinguisher powder had all been removed from the benches and tables after the mayhem of the previous day.
