Russian Su-27 Jet Scrambled to Intercept US Spy Plane Over Black Sea - Military
A Russian Su-27 fighter jet intercepted a US P-8A Poseidon reconnaissance aircraft as it approached Russian airspace over the Black Sea, the Russian Defence Ministry said on Friday.
The ministry said the Armed Forces spotted the aerial target as it approached Russian airspace.
"An Su-27 fighter jet as part of the Southern Military Districts air defences was scrambled to intercept the target. The crew flew the aircraft at a safe distance to the aerial target and identified it as a US P-8A Poseidon reconnaissance jet, which immediately changed the direction of its flight to fly away from the Russian state border," the ministry said in a statement.
The Russian jet carried out its flight in line with international rules. After completing its mission, the Su-27 returned to its home base, according to the military.
Earlier in the day an alleged video of an interception of a US P-8 Poseidon surveillance aircraft by Russian warplanes near the coast of Crimea surfaced online.
