US Air Force Central Command apologized for US planes flying close to Russian jets over Syria said the Russian Defense Ministry.

Axar.az reports referring to the RIA Novosti, the ministry's spokesman, Major-General Igor Konashenkov.
"On October 17, the crew of a US aircraft E-3 AWACS pushed down by almost one kilometer from its height in violation of safety regulations and dangerously close approached a Russian Su-35 fighter jet in violation of all air safety rules in [Syrian] airspace near Deir ez-Zor," Maj. Gen. Igor Konashenkov said.

Shortly after the incident, the command of the Russian Aerospace Forces at the Hmeymim airbase in Syria's Latakia contacted the US side asking for explanations.
