"There must be one clear thing - if someone shoots at our planes, we will destroy them".
Speculation has mounted in recent weeks that Russian Federation could deploy the advanced S-300 anti-aircraft missile defense system to Syria, following a US-led airstrike on Syrian military sites and another earlier strike on an Iranian-operated air base in Syria widely attributed to Israel.
Tensions between Israel and Iran have been on the rise following an alleged Israeli attack on the T-4 air base in Syria earlier in April. However, with S-300 air defence systems deployed in the war-torn country, Tel Aviv will have to negotiate with Bashar Assad, military expert Andrei Koshkin believes.
For Russia, this is very much the point, attempting to deter future USA attacks. "If they're used against us, we'll act against them".
"On the claim the Russians have an "intact" Tomahawk, we have seen no verifiable proof, other than statements made to Russian state-owned media", Pahon said.
Last week, Lavrov told the BBC that Russian Federation is no longer bound by its pledge not to supply S-300s to Syria after the April 13 strikes by the U.S., Britain and France against three suspected chemical weapons sites in Syria.
Royce added that "at the same time as this carnage is going on, representatives of Syria, Iran and Russian Federation have spread out across the worldwide community trying to gin up reconstruction money", but "they will not find it here".
"Russian specialists will continue training Syrian military personnel, as well as assist in the development of new air defense systems, the deliveries of which will be carried out in the near future", he said, according to Al-Masdar News.
Iran-allied Syrian forces shooting down an Israeli F-16 fighter jet by Syrian forces and the infiltration of Israeli airspace by an alleged Iranian drone prompted Israel to strike targets linked to the Islamic Republic in February.
The defense minister noted that Russian Federation already has its own S-300 air defense system in Syria, along with the more advanced S-400 system, and that "hasn't limited our operations". Syrian air defences destroyed 70 out of 100 missiles that the coalition launched.
Israeli officials only warned the USA of the strikes. This potential was allegedly concentrated in three Syrian facilities, according to the U.S., the United Kingdom and French leadership, Tass reported Wednesday.
