Syrian air defenses on Monday night responded to a missile attack over Homs, Syria's official news agency SANA reported.
According to the report, the missiles targeted the Shayrat air base, which was attacked by the United States last year following a chemical attack in Khan Sheikhun.
All three of the missiles were shot down by the country's air defenses, the report said, but did not specify who may have fired the missiles.
The Pentagon said there were no reports of U.S. military activity in the area.
“There is no U.S. military activity in that area at this time,” Eric Pahon, a Pentagon spokesman said, according to Reuters. “We do not have additional details to provide.”
The missile attack comes three days after the United States, France and Britain launched joint air strikes on Syria in response to the regime’s use of chemical weapons on civilians in Douma.
Last week, seven Iranian personnel were killed in an early morning strike on the T-4 airbase in Homs.
Iran accused Israel of being behind the air strike, as did the Syrian regime and Russia.
