Dozens of vaccine opponents stormed the headquarters of the British news producer ITN in London on Monday.
On Twitter videos you could see a large group of people in the foyer of the production company chanting slogans against vaccinations and corona measures.
A news anchor who entered the building was exposed to harsh abuse.
Sometimes there was also a scramble with police officers who tried to prevent people from entering the editorial offices further.
ITN produces the news programs for UK broadcasters ITV, Channel 4 and Channel 5. "Insulting journalists for their reporting is a worrying development that ITN has been following closely and actively encouraging its staff to take precautions to avoid harm" said an ITN spokesman.
