"The United States express grief over the loss of the crew of the Russian aircraft, which was shot down by the fire of the air defense of the Syrian regime," the diplomat said in a statement.
According to him, the incident "reminds us of the need to find a permanent, peaceful and political solution to the many overlapping conflicts in the region and the danger of tragic miscalculations in the Syrian theater of operations."
Earlier, the US Mission to the United Nations expressed its condolences in connection with the crash of the IL-20.
The Russian Defense Ministry said that the incident was due to the fact that the Israeli Air Force pilots covered themselves with Russian aircraft, substituting it for the fire of Syrian air defense weapons.
