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.
Israeli warplanes killed at least 60 people and wounded 58 others in successive airstrikes on the Baalbek-Hermel governorate and the Bekaa Valley in eastern Lebanon on Monday night, according to the Lebanese Ministry of Public Health.

Hezbollah said in a Tuesday morning statement posted to social media that Naim Qassem was elected as the group's new secretary general in a vote by its decision-making Shura Council.
Qassem, 71, was born in the Lebanese capital Beirut. He was previously Hezbollah's deputy secretary general, serving in the role since 1991. Qassem has long been a prominent spokesperson for the Iran-backed militant organization.
His election followed Israel's assassination of former Secretary General Hassan Nasrallah in September and his presumed successor Hashem Safieddine in October.
Following Nasrallah's killing in Beirut, Qassem gave a video address in which he vowed that Hezbollah would continue its fight against Israel despite its significant military setbacks.

The Israel Defense Forces said Tuesday it attacked more than 110 targets in Lebanon and 40 targets in the Gaza Strip in the previous 24 hours.
Hezbollah targets in Lebanon included "launchers aimed at the rear of the state of Israel and weapons depots," the force wrote in a post to X.
In Gaza, the IDF said it attacked "terrorist cells, military buildings and other terrorist infrastructures."
UN Secretary-General António Guterres is "deeply concerned" by the two laws passed by the Israeli parliament Monday concerning the U.N. organization, UNRWA, he said in a statement Monday.
"UNRWA is the principal means by which essential assistance is supplied to Palestine refugees in the Occupied Palestinian Territory. There is no alternative to UNRWA," the UN Secretary-General said in the statement.
"The implementation of the laws could have devastating consequences for Palestine refugees in the Occupied Palestinian Territory, which is unacceptable," he added.
