Home secretary Amber Rudd has confirmed that police are treating an attack near Finsbury Park Mosque as a terrorist incident.
One man died and 10 people were injured after a van drove into pedestrians near the mosque in Seven Sisters Road, north London, in the early hours of this morning.
Rudd was asked why the Metropolitan Police did not immediately refer to what had happened as terrorism, however, she said: "It was treated immediately as a suspected terrorist attack. We must allow the police to deal with the fact, and they will make sure they make those facts available as soon as they can."
She added: "Londoners have been hit with a series of attacks and have actually been nothing short of heroic."
The home secretary said no details are known about the attacker "at this time".
She confirmed that the Prime Minister will chair a meeting of the Cobra committee today.
Rudd was also questioned over funding for emergency services, in light of the recent terror attacks across the UK and last week's tragic fire at Grenfell Tower.
"They have generally confirmed to us that they do have sufficient resources, because there is a kind of mutual aid that works, of people supporting each other," she said.
"Mutual aid that went to help people in Manchester, mutual aid that helps people in London. And it is working. But of course we will always keep it under review to ensure that our emergency services have all the support they need so they can support the communities affected."
