Viktor Zavarzin, a member of the Russian parliament’s defense committee, has warned that Russia will not leave the downing of the Su-24 jet unanswered, TASS reports.
"Our miitary aircraft did not violate Turkish air space," Zavarzin said.
"Today's incident is a serious provocation for regional and global security, the consequences of which will be irreversible...From the Russian side there will be an appropriate reaction, a response. The actions of the Turkish authorities are completely unacceptable, they have made a huge mistake."
Zavarzin added that "everyone is threatened by IS. And we can only fight it together...But now we see that many are clearly hindering our fight against terror. That's why what happened, happened."
Here's the video obtained by Reuters from a Syrian rebel group calling itself the 10th Brigade purports to show one of the pilots from the Russian plane shot down near the Syrian-Turkish border.
Russia's Izvestia news site is reporting that the Su-24 jet would not have stood a chance against an F-16, because Su-24s are designed exclusively for bombing from the air, not air battles and have a higher take off weight and lower maneuverability than F-16s.
Turkey and now Russia say that a the Su-24 was shot down by a Turkish F-16.
Izvestia spoke to Mikhail Khodarenko, the editor-in-chief of the Military Industrial Courier weekly magazine, who said that the pilots of the Su-24 may not have even noticed the F-16.
"The Su-24 does not have a rear view mirror in its cockpit. The pilots sometimes even use a hand mirror in order to at least roughly see what's going on behind them," Khodarenko said.
"Regarding ejection, in the Su-24 it's not automatic. There are two levers between the pilot's legs which need to be raised in order to eject."
There have been more reactions from Russian lawmakers to the downing of the Russian Su-24 jet by Turkey this morning.
Alexander Romanovich, a member of Russia's social democrat A Just Russia party who is also deputy head of the Duma's international affairs committee, said that the incident has dealt a blow to Russian relations with Turkey, and that Russians would change their attitude toward the country.
"I'm sure that Turkey will suffer serious economic damage if only because of the attitude of Russians," Romanovich said.
