Three British teenagers suspected of trying to travel to Syria have been detained by authorities in Turkey, Scotland Yard has said.
The three Britons – two boys aged 17 from north west London and one man aged 19 – were detained in Istanbul.
They were reported missing on Friday and were detained after UK counter terrorism officers alerted Turkish officials, UK police said.
Their families have been “kept informed of developments”, the Met added.
Scotland Yard said counter terrorism officers had initially been made aware that the two 17-year-old boys had gone missing and were believed to be travelling to Syria.
Enquiries revealed they had travelled with a third man, police said.
“Officers alerted the Turkish authorities who were able to intercept all three males, preventing travel to Syria. They remain in detention in Turkey,” a police spokesman added.
