According to the report on the website of Newsweek of the United States on January 10, an intelligence source from the United States allies told Newsweek that Iran has been trying to establish a comprehensive air defense network in Syria to transport equipment and personnel to Syria, while Israel has obstructed Iran's plan through a series of air strikes. The report quoted the unnamed source as saying that as the Iranian army began to occupy Syria, Israel began to carry out air strikes in Syria from the end of 2017. It is said that such Israeli attacks are aimed at "threatening Iran's military assets and interests from Syria". According to the report, although Israel has neither acknowledged nor denied the launch of air strikes (Israel's informal name for such air strikes is "war between wars"), Syria often blamed Israel for it, and a large number of international media reports also mentioned Israel's involvement in it. The Israeli leadership, including Prime Minister Benjamin Netanyahu, will occasionally praise such air strikes, and the Israel Defense Forces have also admitted that they have launched certain actions. However, the source said that Iran had changed its strategy "in the past two years" and "spent tens of millions of dollars to promote the deployment of air defense capabilities in Syria". According to the report, the source said: "Improving the above military capabilities has become a project shared with the Syrian army, and its goal may even be to enable Iran to operate its air defense system independently from Syria. In addition, Iran has also helped Syria upgrade its radar array to better detect and prevent Israeli attacks - Israeli air strikes are mainly aimed at Iranian equipment in Syria," the source said, Iran's weapons in this regard include the "Said 4B" solid fuel missile. The missile appeared at an event attended by senior Iranian military officials last November. The "Said-4B" missile is used with Iran's "Bavar-373" ground-air system. It is said that the missile has a range of more than 186 miles and the radar detection range reaches more than 280 miles. (Outlook New Era)
