Two days ago the Syrian army has acknowledged that Syrian rockets were fired at Israeli aircraft in Syria.
One of the missiles managed to shoot down, the other two fell to the ground in Israeli territory. Israeli planes have not been damaged.
This is the first combat use of the complex Arrow which is part of the Israeli missile defense system.
According to military observer bi-Bi-si Jonathan Marcus, this incident, which became known from the official statement of the defense Army of Israel marks a serious escalation of tensions between Israel and Syria.
In early March, ago, Israeli Prime Minister Benjamin Netanyahu visited Moscow, where he met with President Putin. Russian radars and aircraft control much of Syria's airspace.
Probably, this episode can also be interpreted as a signal to all involved parties that if the supply of arms to Hezbollah will continue, Israel is ready to escalate its air campaign.
