On the same day that Russia announced the delivery of another batch of Sukhoi Su-34 bombers, Ukraine claimed to have destroyed six aircraft at the Morozovsk base, about 80 miles (130 km) from the border.
The Russian base hosts Su-27 fighters and the same Su-34 bombers, but Ukraine did not detail which aircraft it destroyed in the attack.
Ukrainian security sources also told the BBC that eight planes were severely damaged. There was no official confirmation of the attack.

Meanwhile, the United Aircraft Corporation (UAC) announced on its website that it had delivered the first batch of Su-34 bombers, supersonic jets based on the Su-27 fighter but with side-by-side seating.
The aircraft were manufactured in Novosibirsk, in the far east of the country. The images released show at least two Su-34s, but as is customary, the UAC does not reveal numbers and digitally erases the identification markings on the fuselage.

“We have started delivering aircraft with the first batch of front-line Su-34 bombers as part of this year’s production program,” said Yuri Slyusar, General Director of UAC.
The plant also produces the Su-35 and Su-57 fighters, this one of the 5th generation and with stealth capabilities.
