The Russian defence ministry claimed the two US planes approached the Russian border over the Black Sea. It said the Russian fighter approached the US strategic reconnaissance aircraft RC-135 and P-8A Poseidon patrolling plane.
“The American reconnaissance planes were not allowed to breach the Russian Federation’s state border,” the Russian ministry said in a statement.
It comes just days after Russia said it intercepted a US spy plane over the Black Sea.
Earlier this week, in an announcement made by Russia’s official news agency, TASS, the Russian defence ministry said a SU-27 fighter jet had made the interception.
The defence ministry also claimed a US surveillance plane was identified flying near to the Russian border.
The aircraft was identified by the ministry as a P-8 Poseidon – which is said to have then veered away from Russian airspace.
The ministry clearly stated no permission had been given for the path of the plane on Monday.
The jet scrambled by Russia earlier this week was a Su-27 twin-engine fighter aircraft – which can travel at twice the speed of sound and reach up to 1,553mph (2,500kph).
It marks an increasingly tense period between the two superpowers.
At the end of June, US F-22 stealth fighter aircraft were scrambled to intercept four Russian reconnaissance planes off Alaska, accoridng to NORAD, the US and Canadian defense organisation.
They claimed the interception marked the 10th time this year Russian military aircraft had been intercepted near Alaska.
The Russian aircraft did not enter US or Canadian sovereign airspace, NORAD said.
And, just days before on June 19, TASS reported Su-30, Su-35 and MiG-31 fighter jets of Russia’s Eastern Military District were scrambled to intercept US Air Force B-52H bombers, the Defense Ministry’s National Defense Control Center said.
“On June 19, 2020, the air defence quick reaction alert forces of the Eastern Military District spotted and started tracking a pair of US Air Force B-52H bombers over the Sea of Okhotsk,” the Center added.
Again, no violations of Russia’s state border were allowed, the National Defense Control Center insisted.
It comes as Donald Trump announced plans to reduce US troop numbers in Germany, instructing the United States European Command (EUCOM) to be moved from Stuttgart to Mons, near Brussels.
Mons is where NATO has its Supreme Headquarters Allied Powers Europe (SHAPE), the defence alliance’s top military command.
President Trump announced his intention last month to cut the US troop contingent in Germany by about a third, saying Berlin had been taking advantage of the United States while not meeting financial obligations to NATO.
