Protesters force US university to cancel talk with controversial UK journalist
A talk by a controversial journalist at a US university was cancelled after protesters threw smoke bombs and started a fire.
Breitbart News editor Milo Yiannopoulos had been due to speak at the University of California, Berkeley.
It was the last stop of a tour aimed at defying what he calls an epidemic of political correctness on college campuses.
The British 32-year-old is a vocal supporter of President Donald Trump and a self-proclaimed internet troll whose comments have been criticised as racist, misogynist, anti-Muslim and white supremacist.
University spokesman Dan Mogulos said officials were advising the campus to shelter in place and to stay away from the student union building, where Mr Yiannopoulos was scheduled to speak.
A group of protesters dressed in black and some in hooded sweatshirts broke windows, threw smoke bombs and flares at a building and started a large bonfire outside the building.
Some protesters began pulling away metal barricades as police in riot gear guarded the building.
Hundreds of peaceful demonstrators carrying signs that read "Hate Speech Is Not Free Speech" had been protesting for hours before the event.
The visit to Berkeley was sponsored by the campus Republican club.
Several of Mr Yiannopoulous' talks at other campuses had previously been cancelled due to protests or security concerns.
