The United States and its so-called coalition partners have conducted at least two airstrikes in Syria and 11 in Iraq, the Pentagon says.
According to US military officials, the attacks targeted Daesh (ISIL) terrorists and were carried out on Tuesday, a day after Washington air-dropped tons of weapons to militants fighting inside Syria.
"Coalition forces conducted an airdrop Sunday in northern Syria to resupply local counter-ISIL ground forces as they conduct operations against ISIL," US Central Command spokesman Colonel Patrick Ryder said in a statement on Monday, using an acronym for the Daesh terrorist group.
"The aircraft delivery included small arms ammunition to resupply counter-ISIL ground forces so that they can continue operations against ISIL," he added.
A US official, who spoke on condition of anonymity, told AFP the material included 50 tons of ammunition.
The airstrikes come nearly two weeks after Russia began its military campaign against terrorists fighting against the Syrian government. Russia has carried out scores of airstrikes against terrorists there, killing hundreds of them.
On Wednesday, Russia fired 26 long-range cruise missiles from its warships in the Caspian Sea against terrorists in Syria.
