US fighter jets struck Syrian targets in an operation launched against Islamic State militants from the Incirlik airbase in Turkey, the US military confirmed Wednesday. This news comes amid reports of a renewed rebel offensive on Syrian government forces. Six F-16 strike fighters were deployed to Incirlik Airbase near Adana in southeastern Turkey earlier this week. The US forces stationed there have already been conducting drone operations against Islamic State (IS, also known as ISIS/ISIL), but Wednesday’s strikes were the first manned missions staged from Turkey under an arrangement reached with the government of President Erdogan in July. “The United States and Turkey, as members of the 60-plus nation coalition, are committed to the fight against ISIL in the pursuit of peace and stability in the region,” said a statement from the US mission to NATO announcing the fighters’ deployment on August 9. No Turkish fighter jets were involved in the strikes, security sources told Reuters. Ankara has been reluctant to take part in the campaign against Islamic State militants, citing “fears of backlash.” Western critics have slammed Ankara’s stance, considering that Turkish planes are currently flying bombing sorties against the Kurdish militias based in Syria and Iraq, but not against IS militants on the same territory. Ankara considers the Kurds to be a threat to Turkey’s integrity, labeling them as terrorists. However, they have been the only ground force in the region to have any success fighting Islamic State.
