Turkey has again summoned the Russian ambassador after a second violation of its airspace by a Russian warplane operating in Syria in two days, the BBC reports.

It did the same after the first violation on Saturday, after which two Turkish F-16 jets were scrambled.

Turkey said the second violation occurred on Sunday.

Russia said Saturday’s violation was for just a few seconds and due to poor weather. It has not officially reacted to Sunday’s incident.

Saturday’s interception took place near Yayladagi in the southern Hatay region, Turkey says.
