US Secretary of State John Kerry strongly condemned Russia over its decision to sell an advanced missile system to Damascus, considering it puts Israel at risk.

Speaking from Washington, Kerry also warned that the planned delivery of S-300 air defense missiles to Damascus “was not helpful” as Russia and the US prepare for Geneva 2, to try to end the Syrian conflict.

Kerry said the delivery would have a “profoundly negative impact on the balance of interests and the stability of the region, and it does put Israel at risk”.

It is “not helpful to have the S-300 transferred to the region while you are trying to organize this peace and create peace," he added, questioning whether Russia was “fully committed to ending Syria's conflict”.
