Turkey's military says a high-level Russian air force delegation has arrived in Ankara to discuss Russian jets' violation of Turkey's airspace.

A military statement said the delegation, led by Russia's deputy air force commander, "shared information" on Thursday on the reasons for the two intrusions that happened earlier this month, as well as measures that Russia was taking to avoid further incidents.

The violations drew strong reaction from Turkey and its NATO allies.

Turkey has also strongly criticized Russia for targeting moderate rebels during the military campaign in Syria and warned Moscow risked harming trade ties with Ankara.
