A man who was arrested at Londons Heathrow Airport after he arrived on a flight from Turkey will appear in court on Monday on charges of preparation of terrorist acts, British police said. Mamun Rashid, 26, was arrested on Thursday on suspicion of offences related to the conflict in Syria. Counter-terrorism police detained him hours after Turkey said it deported a British man linked to ISIS terrorist organization. Turkish authorities have begun to send ISIS detainees back to their home countries.
