The Russian Defense Ministry on Saturday confirmed that the Aerospace Force had destroyed a protected command and an underground bunker of the ISIL, including an arsenal of explosives, near the city of Raqqa.
In order to destroy that fortress, a Sukhoi (Su-34) fighter dropped a Betab-50 freefall bomb designed to perforate solid structures like concrete, Major General Igor Konashenkov, the Spokesman for the Ministry of Defense, explained.
According to the spokesman, over the past 24 hours, 20 missions were carried out against nine infrastructure targets of the terrorist group, six of which took place at night.
On Friday Russian President Vladimir Putin explained in Paris to his French counterpart, François Hollande, that the Kremlin's support for the Syrian Army's offensive is aimed at preserving the country's territorial integrity.
He added that during the operation carried out at Syria's request and respecting international law, Russia is willing to coordinate the information and continue seeking a settlement to the conflict with all parties involved.
He stressed that the air strikes are against the ISIL, the Al-Qaeda-linked Al-Nusra Front and other groups, according to Presidential Spokesman Dmitri Peskov.
In contrast to Russia's stance, US President Barack Obama told a news conference that Washington will maintain its support for what he called ‘groups opposed to the government,’ because "the problem here is Assad."
