A Turkish official says authorities have begun deporting back to Britain nine British citizens who were arrested trying to cross into Syria.

One of the group, the son of a local politician in Britain, was expelled late Monday, and the other eight were expected to fly back Tuesday from the southern city of Antalya to Manchester.

The official, who spoke on condition of anonymity because of rules against commenting without prior authorization, said the group bought their own airline tickets.

The group was detained in Hatay province, bordering Syria, on April 1 and comprised three men, two women and four children aged 1 to 11.

The nine are among a spate of recent cases of U.K. citizens trying to reach areas of Syria controlled by the Islamic State group.
