Milo Yiannopoulos' speech cancelled after violent protests

A speech by the Breitbart editor Milo Yiannopoulos, who describes himself as "Trump-supporting provocateur", was cancelled on Wednesday at the University of California, Berkeley after more than 1,500 protestors turned violent. Anti-Trump protestors shot fireworks at police, broke windows, started fires and threw barricades at the speech venue but celebrated after the event was cancelled.
