Two teenagers have been arrested for alleged terrorism offences in Greater Manchester.
The 16-year-old girl and 16-year-old boy were arrested on Monday in the Mossley area of Tameside by the North West Counter Terrorism Unit.
The pair were arrested on suspicion of being concerned in the commission, preparation or instigation of an act of terrorism.
They remain in police custody while searches continue at Hanover Street and Spring Mill Drive in Mossley.
Greater Manchester Police expected the searches to last some time.
Chief superintendent Caroline Ball said: "I know news of an arrest made under terrorism legislation in this community will cause a certain amount of anxiety and people will understandably have questions.
"What I want to stress very clearly is that this investigation is in no way linked to any sort of international terrorist plot nor have we recovered any evidence to suggest the community of Mossley is at risk.
"This investigation has arisen as a result of information from law enforcement agencies so it is prudent we act on that information and carry out a thorough, professional investigation to determine the circumstances and details of the activity reported.
"Members of our community will see a lot of police activity at these addresses over the coming days but rather than cause anxiety I want people to be reassured that we have taken this precautionary action to ensure the safety of our residents."
