A Russian SU-34 jet violated Turkish airspace on Friday despite radar warnings, Turkey's foreign ministry said on Saturday, amid ongoing bitterness between the two countries involved in Syria's war.
The Russian ambassador was summoned over the incident late on Friday, the statement said, adding that the violation was a clear sign that Russia wanted issues between the two countries to escalate.
"We are making a clear call to the Russian Federation not to violate Turkish airspace, which is also NATO airspace," the statement said.
