Iranian-backed militias and proxies might be coordinating a strike against American military forces in the Middle East, according to a recent U.S. intelligence assessment.

Three defense officials told CNN that these threats are within Syria and other parts of the region. “They all describe the potential threat as ongoing and worrisome,” according to the outlet. “However, they would not describe the specific intelligence that continues to be gathered.”

This development comes amid the Israel Defense Forces releasing ‎images on Thursday of Hezbollah facilities in ‎Lebanon’s capital, noting that they demonstrated the Shi’ite terrorist group ‎is trying to build weapon-production sites near the Beirut airport. ‎

In his address to the U.N. General Assembly on Thursday, Israeli Prime Minister Benjamin Netanyahu warned about the Iranian threat, showing evidence gathered by the IDF of secret missiles in Lebanon.

“Hezbollah is using the innocent people of Beirut as human shields,” said Netanyahu, holding up a photo of a missile site beneath a soccer stadium. “Israel also knows what you are doing.”

Netanyahu met with U.S. President Donald Trump in New York during the U.N. Security Council proceedings, whom he said agreed to everything he requested on behalf of Israel.
