Russia has deployed more units of its S-400 long-range surface-to-air missile system to Syria.

On Tuesday, Russian-state media released footage of the arrival of additional S-400 long-range surface-to-air missile (SAM) via sea-lifters to the Syrian port city.

From the airbase near Latakia the S-400’s surface-to-air missiles could strike targets in an arc that takes in much of Israel; the eastern Mediterranean (including Cyprus where British jets are based); and northwards to cover a large part of Turkey beyond the Syrian border.

The S-400 is the latest generation of Russian mobile anti-aircraft systems currently in service. It is designed to engage aerodynamic targets and ballistic missiles.

Russia now has two S-400 air defence systems deployed in Syria
