Following the Golders Green stabbing attacks today, the UK terrorism threat level has been raised from "substantial" (an attack is likely in the next six months) to "severe" (an attack is highly likely).
The Joint Terrorism Analysis Centre says the increase follows yesterday's stabbings in Golders Green, but "is not solely a result of that attack."
Two Jewish men - Shloime Rand 34 and 76-year-old Moshe Shine - were attacked on Wednesday. Police are treating it as a terrorist incident.
