Following the dastardly Paris terror attacks and the bombing of a Russian passenger plane in recent weeks, Russian pilots are dropping bombs on Isis targets in Syria inscribed with the messages 'For Paris' and For Our Guys'. 

"Pilots and technicians of Hmeymim airbase have sent their message to terrorists by priority airmail," the Russian Defence Ministry said as it shared a video that showed its pilots writing 'For Paris' and 'For Our Guys' on FAB-250/M62 bombs.

Russia reportedly increased the intensity of its airstrikes against Isis after it confirmed earlier this week that its passenger plane was brought down by a bomb on board as it flew over Egypt's Sinai Peninsula last month. 

The Russian warplanes have reportedly destroyed at least 800 Isis targets in Syria in the last four days alone, as per reports. 

On Friday alone, a Russian airstrike in Syria's Deir el Zour is said to have killed 600 Isis fighters.

Pilots striking Isis targets are known to inscribe messages on missiles and bombs 

Earlier this year, following the brutal execution of a Jordanian pilot by Isis, Jordanian fighter jets bombarded the Islamic State with missiles scribbled with messages that read "For you, the enemies of Islam."
