Strike on U.S. Base Was Iranian Response to Israeli Attack, Officials Say

An armed drone strike last month on an American military base in southern Syria was Iranian retaliation for Israeli airstrikes in Syria, according to eight American and Israeli officials who spoke on the condition of anonymity to discuss intelligence matters.

The drone attack, which caused no casualties, would be the first time Iran has directed a military strike against the United States in response to an attack by Israel, an escalation of Iran’s shadow war with Israel that poses new dangers to U.S. forces in the Middle East.

Five so-called suicide drones were launched at the American base at Al Tanf on Oct. 20 in what the U.S. Central Command called a “deliberate and coordinated” attack. Only two detonated on impact, but they were loaded with ball bearings and shrapnel with a “clear intent to kill,” a senior U.S. military official said.

Most of the 200 American troops stationed at the base, whose main role is training Syrian militias to fight the Islamic State, had been evacuated hours earlier after being tipped off by Israeli intelligence, the officials said.
