Russia's ministry of defence released video on Thursday (March 31) of Russian military helicopters and jets hitting Islamic State facilities in the Syrian city of Palmyra. <br /> <br />Among the targets destroyed by Russian MI28 helicopters and jets were an armoured vehicle, an ammunition depot and buildings belonging to to IS, the ministry said. <br /> <br />Syrian government forces backed by heavy Russian air support drove Islamic State out of Palmyra on Sunday (March 27), inflicting what the army called a mortal blow to militants who seized the city last year and dynamited parts of its ancient temples. <br /> <br />The loss of Palmyra represents one of the biggest setbacks for the ultra-hardline Islamist group since it declared a caliphate in 2014 across large parts of Syria and Iraq.
