Footage released on Monday shows the moment a Tu-22M3 strategic bomber dropped ordnance on militant positions in Deir-Ezzur after taking off from an unknown military base in Russia. 

The Syrian Army has regained control of large territories in Latakia province with support from the Russian Air Force, with terrorists now redeploying forces to eastern parts of the country, the Russian Defense Ministry said on Monday.

Having lost their advantage in western parts of the country, IS command has now decided to concentrate its forces on trying to seize the city of Deir ez-Zor, the largest city in the eastern part of Syria, the Russian Defense Ministry said. Up to 2,000 heavily armed militants have been redeployed by IS to the region, the ministry added, citing data received from Syrian opposition and the information center in Baghdad.
