WASHINGTON (Sputnik) — The US Department of Defense cannot confirm that Russian forces carried out the strikes along the Syria-Jordan border earlier this week that hit the moderate Syrian opposition, US Department of Defense spokesperson Peter Cook said in a briefing on Thursday.
"I cannot confirm with a 100 percent certainty that the Russians carried out those strikes," Cook stated. "Our understanding is these were strikes that did hit moderate opposition forces that had been fighting ISIL [Islamic State]."
The Defense Department spokesperson noted that the United States is concerned with the airstrikes along the Syria-Jordan border as there had been an indication that some civilians were killed.
US media claimed on Tuesday that Russian airstrikes hit a refugee camp along Jordanian border with Syria.
Syria has been mired in civil war since 2011, with government forces loyal to President Bashar Assad fighting a number of opposition factions and extremist groups.
On February 27, a US-Russia brokered ceasefire came into force in Syria. Terrorist groups such as Islamic State, as well as Nusra Front, both outlawed in Russia and a range of other states, are not part of the deal.
