Three teenagers, at least two of them British, were stopped by Turkish authorities as they attempted to travel to Syria, London police said Sunday.
Two were 17-year-old boys from northwest London who had gone missing, a Metropolitan Police news release said.
They were traveling with a 19-year-old, the release said, without providing additional information on the man. Several media outlets, including BBC and Reuters, reported he, too, was British.
They were detained Friday.
British counterterrorism officers “alerted the Turkish authorities who were able to intercept all three males, preventing travel to Syria. They remain in detention in Turkey. The families have been kept informed of developments,” the news release said.
Sunday’s news come on the heels of developments in the case of three British girls who are believed to have entered Syria to join ISIS.
Turkey on Thursday arrested a person who worked for an undisclosed nation’s intelligence service on suspicion of helping the girls, according to Turkey’s foreign minister.
On Friday, a Turkish television network aired a video purportedly showing the girls preparing to cross the Turkish border into Syria.
