U.S. approach Russia, Syria to avoid escalation of violence

The United States on Tuesday warned against an escalation of violence in northwest Syria, saying any such action "will result in the destabilization of the region."

"We call on all parties, including Russia and the Syrian regime, to abide by their commitments to avoid large scale military offensives, return to a de-escalation of violence in the area, and allow for unhindered humanitarian access," the U.S. State Department said in a statement.
