NATO held an emergency meeting late Monday, after Russia violated Turkish airspace twice in two days during airstrikes on Syria. 

In the first incident, an SU-30 fighter aircraft had entered Turkish airspace “for a few seconds" because of bad weather, Moscow stated Saturday. 

However, since then, yet another incident has been reported, a Turkish foreign ministry official stated Monday night - and warned that Russia would “be responsible for any undesired incident that may occur” if it happened again. 

Tuesday morning, Ankara announced it had summoned the Russian ambassador to Turkey to "strongly protest" the airspace violations, AFP reported. 

NATO Secretary-General Jens Stoltenberg stated Tuesday that Russia has not given "any real explanation" for its extended violation of Turkish airspace. As a result, he concluded that the issue "does not look like an accident."

Russia began to carry out airstrikes in Syria last Wednesday. Stoltenberg has since called on Moscow to be careful not to further escalate the tensions between Russia and NATO.

Reports have shown that the strikes have killed a number of civilians, though Russian President Vladimir Putin denies the charges.
