As the world reels from the killing of 10 journalists and two police officers in Paris, London is on guard.
Additional police and armed officers have been brought in for security at the Houses of Parliament, the Palace of Westminster and at least one magazine’s office in London, the Telegraph reports.
The magazine has not been named, but is reportedly one that has published articles critical of radical Islam.
The organisation has apparently been told to keep the front door locked.
A Met Police spokesperson told the Telegraph that they do not discuss security arrangements.
