In the early hours of Monday morning, a 48 year old man allegedly ran a van into unsuspecting Muslims who had been praying at a Mosque in the Finsbury Park section of London.

The driver was taken into custody after being detained by bystanders at the scene. 10 people were injured in the attack and one man has died, although it's unclear whether that was directly a result of the attack.

In response, Prime Minister Theresa May said:

"It is a reminder that terrorism, extremism and hatred take many forms; and our determination to tackle them must be the same whoever is responsible."

She also said police declared it a terrorist incident within eight minutes. This is the U.K.'s fourth terrorist incident in as many months.

This incident takes place less than 2 weeks after ISIS claimed responsibility for a similar van attack on London Bridge, and is being investigated as a possible revenge attack against Muslims.

As one of the witnesses who subdued the attacker, Abdul Rahman, described the attacker:

"When the guy came out from his van he wanted to escape, run away and he was saying 'I want to kill Muslims. 'I want to kill Muslims.'"

ISIS is reportedly using this new attack as a call for more atrocities.

London Mayor Sadiq Khan called this incident a "horrific terrorist attack."

Labour Leader Jeremy Corbyn, who represents the Finsbury Park area in Parliament, called this "an attack on all of us."

Corbyn plans to attend services at the Finsbury Park Mosque later today.
