Austrian law enforcement officials say two teenage girls have been detained on suspicion of seeking to travel to Syria as potential wives for militants fighting there.

Marcus Neher of the Salzburg public prosecutor's office says they were detained in Salzburg and Upper Austria province on Saturday. He says they were "offering themselves as spouses for IS fighters."

Neher declined to give further details Sunday. The Austria Press Agency says the Salzburg suspect was 16 and originally came from Chechnya, while the other girl was 17 and born in Bosnia.

APA says the two were detained after investigations that began last month when the 16-year old was turned back to Austria by Romanian authorities while en route to Syria. She is suspected of recruiting potential IS wives, including the 17-year old.
