London police say one suspect has been detained in an apparent early-morning attack on worshippers standing outside a mosque.
- Jeremy Corbyn, the leader of Britain's opposition Labour Party tweeted "I'm totally shocked at the incident at Finsbury Park tonight".
The incident comes weeks after a van hit pedestrians on London Bridge and knife-wielding attackers killed eight people nearby.
The Metropolitan Police said that one man was pronounced dead at the scene and eight others were injured.
The incident occurred in the Seven Sisters Road area, outside the Finsbury Park mosque.
"From the window, I started hearing a lot of yelling and screeching, a lot of chaos outside".
The attack comes at a time of political turmoil in Britain, as Prime Minister May plunges into divorce talks with the European Union weakened by the loss of her parliamentary majority in a June 8 election.
Resident Cynthia Vanzella said she was in bed when she heard people shouting.
The Islington borough of North London, of which Finsbury Park is a part, is home to a large Muslim community.
"This is being treated as a terrorist attack". "There are many Muslims and non-Muslims alike and it's unfortunate that this happened in this area", Kozbar said.
One man died at the scene and 10 people were injured. The Evening Standard newspaper said the van appeared to have been rented in Wales, although there was no immediate confirmation of this from the authorities. Police said a man who was driving the vehicle has been arrested and taken to a hospital as a precaution.
Police said a suspect was quickly and calmly turned over to the police, and that no one else was found in the van. "I didn't see the attacker himself, although he seems to have been arrested, but I did see the van". Many police cars and ambulances were responding.
Cynthia Vanzella, a witness to the van attack, describes the area as a mixed community, with people from many different countries and cultures.
Manchester was also hit by a severe attack when a bomber killed more than 20 people at an Ariana Grande concert.
She said: "We are not saying anything, we don't know anything at the moment". The mosque, which today operates largely as a community center, rose to global notoriety in the early 2000s, due to its links with Egyptian-born radical cleric Abu Hamza al-Masri. On May 22, a suicide attack killed 22 people and injured almost 60 after an Ariana Grande concert in Manchester.
