A Turkish news report says security forces have killed two suspected Islamic State militants at the border with Syria.

Private NTV television said Thursday the two Syrian nationals "were neutralized" after they ignored security forces warnings, but provided no further details. It was not immediately clear if they were trying to cross illegally into Turkey.

NTV, without citing any sources, said one of the two militants was wanted by Turkey on suspicion that he would carry out suicide attacks in the capital Ankara or in the southern city of Adana.

The reported incident comes days after suspected IS militants attacked Istanbul's busiest airport with gunfire and bombs Tuesday, killing 42 people and wounding more than 230 others.
