In a sharp deterioration of relations, the U.S. on Monday suspended diplomatic contacts with Russia over Syria, while Moscow halted cooperation on a joint program for disposal of weapons-grade plutonium.
The U.S. move followed a threat last week from Secretary of State John Kerry after new Russian and Syrian attacks on the city of Aleppo. The State Department said Russia had not lived up to the terms of an agreement last month to restore the cease-fire and ensure sustained deliveries of humanitarian aid to besieged cities.
“This is not a decision that was taken lightly,” State Department spokesman John Kirby said in a statement. “Unfortunately, Russia failed to live up to its own commitments … and was also either unwilling or unable to ensure Syrian regime adherence to the arrangements to which Moscow agreed.”
“Rather, Russia and the Syrian regime have chosen to pursue a military course, inconsistent with the Cessation of Hostilities, as demonstrated by their intensified attacks against civilian areas, targeting of critical infrastructure such as hospitals, and preventing humanitarian aid from reaching civilians in need, including through the September 19 attack on a humanitarian aid convoy,” he said.
An airstrike last month hit a United Nations humanitarian aid convoy, killing 20 people. The United States has accused Russia of hitting the convoy, but both Russia and Syria deny it.
