S-300 missile system: Russia to upgrade Syrian air defences

Russia is to send new anti-aircraft missiles to Syria, a week after Syrian forces accidentally shot down a Russian aircraft during an Israeli air strike.

The S-300 missile defence system will be delivered within two weeks.

The Russian reconnaissance plane was downed last Monday after Israeli jets attacked targets in Latakia province.

Israel, which insisted Syria's military was to blame, warned that giving the S-300 to "irresponsible actors" would make the region more dangerous.

US national security adviser John Bolton said the decision would cause a "significant escalation" in Syria's civil war and urged Russia to reconsider.

Russia to send newer, S-300 missile defense systems to Syria

MOSCOW – Russia announced Monday that it will supply the Syrian government with modern S-300 missile defense systems following last week's downing of a Russian plane by Syria, a friendly fire incident that send regional tensions over the war-torn country soaring.

The Russian military aircraft was downed by Syrian government missile defense systems, killing all 15 people on board. Russia laid the blame squarely on Israel, saying that its fighter jets had pushed the Russian plane into the line of Syria's fire. Shortly before the downing, Israeli strikes had hit targets inside Syria, reportedly preventing an arms shipment going to Iranian-backed Hezbollah group.
