Turkish police have arrested a Danish woman suspected of joining Islamic State in Syria, a state news agency said on Wednesday.
The woman, who is originally from Lebanon, was arrested in the northeastern city of Bursa, Anadolu agency said. She had been sought by Interpol. 
The agency said the woman, who it only identified by the initials AAM, had crossed illegally into Turkey and police found a fake passport in her home.
At the height of Islamic State's self-declared "caliphate", when the militant group controlled parts of Iraq and Syria, Turkey was one of the principal routes for foreign fighters trying to join the jihadists.
Ankara has since cracked down on the frontier and has stepped up arrests and expulsions of suspected foreign IS fighters.
A last group of militants is still battling US-backed Syrian forces in the small area in northeastern Syria left since the collapse of its territory.
Thousands of militant families have fled the last IS bastion as jihadists have surrendered. Among them are the wives and children of foreign militants.
