Secretary of Iran’s Supreme National Security Council (SNSC) Ali Shamkhani said Iran plays a vital role in fighting terror in the region, and that it would identify the time and the manner of punishing the Zionist entity.

He once again reiterated that the Iranian military advisors are present in Syria upon a request by the Arab country's government with the purpose of countering the threat of terrorism and playing a decisive role in defeating terrorist groups in the region.

Shamkhani further said, "The Islamic Republic of Iran has paid a considerable price in order to establish regional stability and fight against Takfiri terrorism. Therefore, it cannot remain indifferent to the worrying increase of destabilizing measures by the US, the Zionist regime (Israel) and some of their regional allies."

Secretary of Iran’s Supreme National Security Council (SNSC) Ali Shamkhani stressed that his country certainly would respond to the Zionist air raid on Syria’s T4 military airport which claimed a number of Iranian advisors.

"Two F-15 planes of the Israeli army hit the airbase between 03:25 am and 03:53 am Moscow time (0025 GMT and 0053 GMT) with the help of eight missiles controlled remotely from Lebanese territory, without entering Syrian air space," the ministry said.

The Syrian state media also reported that the deadly attack was carried out by Israeli warplanes.

"The Israeli attack on the T-4 airport was carried out with F-15 aircraft that fired several missiles from above Lebanese territory," a Syrian military source said.

Shamkhani further said Iran might quit the Non-Proliferation Treaty (NPT) if US President Donald Trump scraps a multilateral nuclear agreement Tehran signed with the P5+1 group of countries in 2015.
