Who really brought down that Russian plane?

One has to ask the question, as news comes out about Russian aircraft ...

It is believed that a 15-year-old schoolgirl was sitting on top of the bomb which blew up the Russian Metrojet plane, killing all 224 people onboard in the Sinai desert. 

Maria Ivleva, from the St Petersburg region, is thought to have been sitting near the bomb which exploded with the same power as one kilogram of TNT. 

A report carried out into the Russian plane crash suggests that investigators have narrowed down where the bomb was put to under the seat of either 30A or 31A in the A321 between Sharm El-Sheikh and St Petersburg. 

Piecing together the report, and the names of victims on the doomed plane, the bomb is believed to have been beneath the seats of either 15-year-old Maria Ivleva, or 77-year-old Nadezhda Bashakova.

Has one story... While this story runs...

BEIRUT — Turkish military aircraft shot down a Russian jet Tuesday after Turkey says it violated its airspace near the border with Syria, a major escalation in the Syrian conflict that could further strain relations between Russia and the West.

Russian officials confirmed that a Russian warplane had been shot down but claimed it had been flying over Syria and had not violated Turkish airspace.

The plane was likely shot down “due to shelling from the ground,” the Russian Ministry of Defense said.

The Russian Defense Ministry said the plane was one of more than three-dozen fixed-wing aircraft flying sorties in Syria as part of Russia’s two-month old bombing campaign there. It is the first Russian plane to crash in that time. 

The incident highlights heightened friction in Syria’s increasingly crowded airspace, which now includes Russian warplanes that are targeting the armed opposition of President Bashar al-Assad’s embattled forces. 

It will almost certainly further strain relations between Russia and the West since Turkey is a member of NATO.

... Don't you think Russia has brought itself into a broader war, as odds would now go against ISIS bringing down the Sinai desert plane crash, and in favor whom Russia was bombing...
