British Prime Minister Theresa May says an attack which left one dead and 10 others injured near a London mosque is being treated by police as a potential terrorist attack.
"Police have confirmed this is being treated as a potential terrorist attack," May said. "I will chair an emergency meeting later this morning."
"All my thoughts are with the victims, their families and the emergency services on the scene," she said.
Earlier, Labour leader Jeremy Corbyn expressed his shock at what had happened, writing on Twitter: "I'm totally shocked at the incident at Finsbury Park tonight.
"I've been in touch with the mosques, police and Islington council regarding the incident. My thoughts are with those and the community affected by this awful event."
