British officials say the number of people being arrested on suspicion of terrorism-related crimes has reached a record high.
The Home Office figures released Thursday show 299 people were arrested in the 12 months that ended in March. Officials say that represents a 31 percent increase over the previous 12 months, and is the highest figure since records started being kept after the September 11, 2001, attacks in the United States.
Officials also report a "marked increase" in the number of suspects who are either British or dual nationals.
