The Israeli military on April 2 carried out air-strikes on several sites in Syria—including Tiyas airbase, also known as T4, and Palmyra airbase, both in Homs province. The interim government in Damascus called the strikes "a blatant violation of international law and Syrian sovereignty." Israeli Defense Minister Israel Katz responded in a statement addressed to President Ahmed al-Sharaa: "If you allow forces hostile to Israel to enter Syria and endanger Israeli security interests—you will pay a very heavy price." This was a barely veiled reference to Turkey. Local media reports indicate that Turkish forces are preparing to deploy to the T4 and Palmyra bases. Ankara reportedly plans to install Hisar-O and Hisar-U air defense systems and potentially the long-range SIPER system at these locations. The deployment of a Russian-made S-400 system is also under consideration, pending Moscow's approval. 

Along with the air-strikes, the IDF is said to have engaged with Syrian forces in a clash near the "security zone" that Israel has seized in Daraa province in the country's south. (BBC News, LWJ)

Turkey has itself bombed Kurdish positions in Syria again and again and again in recent months.
