IDF claims it captured terror operative in Syria
The IDF said it detained a Syrian citizen it alleged was working for Iran.
The Israel Defense Forces conducted what it called "precise strikes on military targets" in Iran on Friday in response to the Iranian missile strikes earlier this month.
Meanwhile, Israeli airstrikes and ground fighting continued in Gaza -- particularly in the north of the strip -- and in Lebanon, with renewed Israeli attacks on Beirut.

US defense secretary speaks to Israeli counterpart about regional de-escalation
U.S. Secretary of Defense Lloyd J. Austin III spoke with Israeli Minister of Defense Yoav Gallant on Thursday to discuss opportunities for regional de-escalation, according to a statement from the Pentagon.
In the call, Austin reaffirmed that the United States remains fully prepared to defend U.S. personnel, Israel and partners across the region against threats from Iran and Iran-backed proxy groups, the Pentagon confirmed.
Austin reiterated the commitment to a diplomatic arrangement in Lebanon that allows both Lebanese and Israeli civilians to return safely to their homes on both sides of the border, according to the statement.
He also reviewed steps Israel is taking — and should continue to advance — to improve the dire humanitarian conditions in Gaza, as well as prospects for a hostage release and cease-fire deal, the statement said.

Iranian general says Israel should expect an 'unimaginable response'
Israel "made a mistake" in attacking Iran over the weekend and will now "taste the response, an unimaginable response," Iran's Revolutionary Guard Corps Commander-in-Chief Gen. Hossein Salami said on Iranian state TV on Thursday.
"You think you can change the story of domination of a great power called Islam by firing a few missiles? In Operation True Promise 2, you saw how your sky was cracked open. You saw how your missile shield worked. Once again you made a mistake, you will taste the response, an unimaginable response," Gen. Salami said.
By "Operation True Promise 2," Gen. Salami is referring to Oct. 1, when Iran sent a barrage of about 200 missiles toward Israel.
"See the behavior of the Iranian nation in the war against its enemies," he added.
