LONDON -- The British counter-terrorism police have declared a stabbing incident in Golders Green, a north-west London neighborhood, on Wednesday a "terrorist incident."

The two victims, aged 76 and 34, suffered stab wounds and are currently in hospital, said Laurence Taylor, head of Counter Terrorism Policing at the Metropolitan Police. The suspect is a 45-year-old man, he added.

Earlier in the day, Jewish community watch group Shomrim said on social media that they detained a man who was seen "running along Golders Green Road armed with a knife and attempting to stab Jewish members of the public."

Metropolitan police officers responding to the incident were also attacked, leading to the tasering and arrest of the suspect, Taylor said, adding that the man was arrested on suspicion of attempted murder and remains in police custody.

Metropolitan Police Commissioner Mark Rowley said the suspect has "a history of serious violence and mental health issues."

British Prime Minister Keir Starmer told Parliament that the incident is "deeply concerning," stressing that lawmakers must be "absolutely clear in our determination to deal with any of these offences, the likes of which we've seen too much recently."

London Mayor Sadiq Khan said on social media that the capital's Jewish community has faced "a series of shocking antisemitic attacks," adding that "there must be absolutely no place for antisemitism in society."
