(AP) – Turkish authorities have detained a Russian national and suspected Islamic State group militant for allegedly planning a drone attack on U.S. aircraft at Turkey’s Incirlik air base, police said Thursday.

Renad Bakiev was detained in the southern city of Adana over suspicions that he plotted to crash an American aircraft or attack the Incirlik air base using a drone, Adana police said in a statement. Turkish private news agency Dogan said a court later ordered him formally arrested pending a trial.

Bakiev also intended to attack the local Alevi community in Adana city, the statement said. It said he was affiliated with IS and had previously traveled to Syria.
