Taking off from the Mozdok airbase in North Ossetia, the bombers carried out strikes on terrorist positions in the Deir ez-Zor province in Syria.
"The targets are over 2,000 km away from the base, and each mission sortie takes at least 5 hours", said base commander Vladimir Alesenko.
He added that the crews make two sorties every 24 hours, with one mission flight taking place at night.
In addition, two Tu-160 strategic missile carriers took off from the Olenya air force base in the Kola peninsula and after covering over 9 500 km and refueling mid-air, deployed missiles targeting terrrorist positions in Syria over the Mediterranean Sea.
"The carriers flew over the Barents and the Norwegian Seas and the Gibraltar Straight before launching strikes and returning to base", said the Olenya base commander Trofim Kapsha.
Overall, the Tu-160 carriers spent over 16 hours in the air.
