A 21-year-old British woman suspected of trying to travel to Islamic State group territory in Syria has been detained in Turkey, government officials said Tuesday.

The woman, identified as J.N.H., was detained at a bus terminal in Ankara late Monday and is being held pending deportation hearings. One of the Turkish officials said authorities apprehended her based on Turkish intelligence and weren't tipped off by British authorities.

The officials say that correspondence and images on the woman's cellphone indicate that she was planning to head to IS territory. The two officials spoke on condition of anonymity because of government rules against speaking to the media without prior authorization.

The woman is among a spate of young British travelers who have come through Turkey and believe to be en route to Syria.

Last week, three British teens were detained by Turkish authorities after arriving from Spain, and deported to Britain.

Last month, three British girls-- identified by British authorities as Shamima Begum, 15, Kadiza Sultana, 16, and Amira Abase, 15 -- traveled from the U.K. to Turkey, from where they are believed to have crossed into Syria.
