"Near Dayr Az Zawr, a strike damaged five ISIL [Daesh] supply routes," Combined Joint Task Force Operation Inherent Resolve said in a press statement published on the US Department of Defense website.
Russian Defense Ministry spokesman Maj. Gen. Igor Konashenkov said on Saturday that coalition planes carried out four attacks on the Syrian government forces near the city, killing 62 servicemen and injuring about 100.
The Operation Inherent Resolve press office declined to comment the issue, referring the question to the US Central Command.
Syria has been mired in civil war since 2011, with government forces loyal to Assad fighting numerous opposition factions and extremist groups, including Daesh, which is outlawed in many countries, including Russia.
The US-led coalition has been carrying out anti-Daesh strikes since September 2014 without Syrian government consent.
