Russian warplanes hit almost 600 terrorist infrastructure facilities in Syria over the past 4 days, completing 157 combat flight missions, Russian Defense Ministry spokesman Igor Konashenkov has said.

"The planes of the Russian aviation group in the Syrian Arab Republic executed 157 sorties targeting 579 facilities of terrorist infrastructure in the provinces of Aleppo, Deir ez-Zor, Homs, Hama, Al-Raqqah, and Latakia," Konashenkov said.

A Sukhoi Su-34 bomber has struck strong points of militants of the 'Islamic State' (the terrorist organization banned in Russia) located on dominating grounds near the populated area of Qabaqlia, the Latakia province, he said.

A direct hit resulted in destruction of four off-road cars equipped with heavy machine guns and neutralization of almost 20 militants.
