“Over the past 24 hours, Sukhoi Su-34 and Su-24M fighter jets have performed 20 sorties and hit nine Islamic State installations,” Igor Konashenkov, Russia’s Defense Ministry spokesman, reported.

Konashenkov added that yesterday evening Russian aircraft went on six sorties, inflicting strikes on three terrorist installations.

“A bunker-busting BETAB-500 air bomb dropped from a Sukhoi Su-34 bomber near Raqqa has eliminated the command post of one of the terror groups, together with an underground storage facility for explosives and munitions,” the spokesman said.

Commenting on the video filmed by a Russian UAV monitoring the assault near Raqqa, Konashenkov noted, “a powerful explosion inside the bunker indicates it was also used for storing a large quantity of munitions.
