A false alarm led to Syrian air defence missiles being fired overnight and no new attack on Syria took place, Syrian state media and a military commander said on Tuesday.
Syrian state-run television reported early Tuesday that the nation's air defenses were confronting a new "aggression", shooting down missiles over the area of Homs in the country's center.
"There is no U.S. military activity in that area at this time", a Pentagon spokesman, Eric Pahon, said.
State television had showed pictures of a missile it said was shot in the air above the air base.
"There is no U.S. military activity in that area at this time", Eric Pahond, a Pentagon spokesman said when asked about the strike on Tuesday. The airbase, located near Homs, was targeted previous year in an American airstrike in response to a chemical weapons attack in Idlib.
The tripartite attack was in ostensible retaliation for an alleged chemical weapons attack by the Assad regime on the Syrian city of Douma, which is said to have killed scores of civilians.
France will spend 50 million euros ($62 million) on new projects in Syria to be carried out by around 20 humanitarian groups, the president's office said Monday.
The reported barrages come three days after a major missile attack by the USA, United Kingdom and France on regime positions in Syria. The strikes raised fears of an escalation of the conflict in which more than 350,000 people have died, but key players on Monday appeared keen to shift the focus to diplomacy.
