British police have arrested four men on suspect of preparing terrorist acts on Britain. The men range in age from 19 to 27. More searches are continuing.
Police reportedly said that the arrests and searches of several properties in west London and the Thames Valley are part of an ongoing investigation into "Islamist related terrorism."
Officials have classified that the threat level in Britain as "severe," meaning a terrorist attack is viewed as highly likely. Police have been warned to be vigilant against attacks on officers.
There have been numerous arrests in recent weeks as police have taken action against some Britons who have returned from fighting in Syria and are feared to be planning attacks in Britain.
