London Mayor Sadiq Khan has urged people to "remain calm and vigilant" a deadly van attack on worshippers leaving a mosque in north London.
"We don't yet know the full details, but this was clearly a deliberate attack on innocent Londoners, many of whom were finishing prayers during the holy month of Ramadan," he said.
"While this appears to be an attack on a particular community, like the terrible attacks in Manchester, Westminster and London Bridge, it is also an assault on all our shared values of tolerance, freedom and respect.
"The situation is still unfolding and I urge all Londoners to remain calm and vigilant.
"The Met have deployed extra police to reassure communities, especially those observing Ramadan."
