BALDWIN: Breaking news. Israel has just conducted an air strike inside Syria. The Israeli defense force says it struck an anti- aircraft system hours after that system fired at an Israeli jet. CNN's Oren Liebermann is with me live from Jerusalem. Oren, what do you know?</s>OREN LIEBERMANN, CNN CORRESPONDENT: Brooke, this is all unfolding in the last 90 minutes or so. Israel says it struck what it called an anti-aircraft system, essentially, an anti-aircraft gun. After earlier in the day, that same anti-aircraft system fired at an Israeli jet the military says was conducting a routine exercise in northern Israel. Israel then targeted that anti-aircraft gun after it launched a shell at the Israeli aircraft. The shell itself remained in Syria. It didn't cross over into Israel. The military says it sees any aggression against its aircraft as very severe and will respond accordingly. Meanwhile, the Syrian state-run SANA news agency says one Syrian soldier was killed and another injured in that Israeli strike. Prime Minister Benjamin Netanyahu issued a statement a short time after this events unfolded, and said, our policy is clear, we're not ready to stand for any aggression against us and we will respond with strength and firmness. Brooke, to the question of, will this lead to an escalation between Israel and Syria? Something we've become all too familiar with, well it's worth pointing out the border between Israel and Syria has been quiet essentially for months now and it seems it's in both country's interests and in the Russian's interests, when they moderate between Israel and Syria to keep a lid on this and to keep a lid on this quickly.</s>BALDWIN: We will stay in close contact with you as the story will develop today. Oren Liebermann in Jerusalem. Oren, thank you very much. And thank you for being with me on this Memorial Day Monday. I'm Brooke Baldwin. "THE LEAD" starts right now.
