London’s Metropolitan Police said on Sunday that 12 arrests had been made in the wake of last night’s attack at London Bridge, which was deemed an act of terrorism.

Police flooded London streets after at least seven people were killed in an area teeming with revelers late Saturday. A van filled with three armed men mowed down pedestrians on London Bridge, with all three attackers shot dead by police within minutes of the attack, Britain’s third major terror incident in as many months.

An outlet affiliated with Islamic State claimed [it] was responsibility for the incident, but NBC was not immediately able to independently verify the claim of responsibility. Still, the ensuing chaos — in a country still shaken by last month’s bombing at a Manchester concert as well as an attack outside Parliament in March— quickly reverberated around the world.

Among the 12 arrested in the Barking area of London were 7 women, according to an official Met Police statement that did not name the suspects. Officials warned of an increased police presence around the city, with investigators still chasing leads and potentially arresting others.
