Turkey says Russian warplane violated its airspace
The Foreign Ministry summoned Moscow's ambassador to protest the violation, according to an e-mailed statement. Turkey urged Russia to avoid repeating such a violation, or it would be held "responsible for any undesired incident that may occur."
Foreign Minister Feridun Sinirlioglu spoke with his Russian counterpart Sergei Lavrov, as well as key NATO partners, the statement said. Russia launched air strikes last week against forces opposed to Syrian President Bashar al-Assad.
