U.S. Weapons from Iraq Making Their Way to Turkey

"Sixty of the 140 guns captured by our team in the last six months are Glocks," Tasan told reporters. "We have observed an increase in the demand for these weapons."

Turkish officials say this seizure is just the tip of the iceberg.

Last month, the Turkish government announced it was finding disturbingly high numbers of weapons of apparent American origin, including Glock pistols, AK-47s and M-16s, in the hands of captured Kurdish separatists from the Kurdistan Workers Party, or PKK.

The PKK has battled the Turkish state since 1984, operating from camps in mountains along the Iraqi border. Both the United States and its NATO ally, Turkey, officially label the PKK a terrorist organization.

"When we searched the origin of the weapons that were seized on some of the terrorists, we noticed that these are the [same] ones given to the Iraqi army," Turkish Foreign Minister Abdullah Gul said in a television interview on July 16. "We asked for clarification from the Americans."
