According to media reports, the Russian military reinforced its air force group at the Hmeimim Air Base near the city of Jableh with four additional Su-34 fighter bombers.
The warplanes were escorted by Tu-154 aircraft, a method used by the Russian Aerospace Forces for transporting warplanes to Syria. The Tu-154 is used as a guide for other fighters throughout the way, and may be used to hide the bombers from the American radars in the Persian Gulf and Iraq.
The Russian fighter jets deployed in Hmeimim continued carrying out multiple airstrikes on terrorist positions throughout Syria.
On April 23, the Russian Aerospace Forces paid a special attention to the militant-held town of Lataminah and provided a close-air-support to the Syrian Arab Army in the Hama offensive.
Russian jets carried out a number of raids pounding ISIS positions in Deir Ezzorr and in the vicinity of Palmyra.
The deployment of the four additional bombers brings the number of Su-34 bombers in Syria up to 12/
The Russian air force group deployed in Hmeimim reportedly includes 12 Su-24M2 bombers, four Su-30SM fighters, four Su-35 fighters and four close air support Su-25sm fighter jets along with a range of service aircrafts.
