"We are prepared to sustain this pressure, if the Syrian regime is foolish enough to test our will," Haley said.
"That failure is largely due to Russian obstruction. We call on Russia to take a hard look at the company it keeps, and live up to its responsibilities as a Permanent Member of the Council and defend the actual principles the United Nations was meant to promote," she said.
The first target included the Syrian Scientific Studies and Research Centre at al-Mazzah Airport in Damascus; the second, an alleged chemical weapons storage facility west of Homs; and the third, an alleged chemical weapons equipment storage site and command post, also near Homs.
Guterres said the Security Council has primary responsibility for the maintenance of international peace and security and called on the members of the Security Council to unite and exercise that responsibility.
"I urge all member states to show restraint in these dangerous circumstances and to avoid any acts that could escalate matters and worsen the suffering of the Syrian people," the UN Secretary General said.
Guterres emphasised that there is no military solution to the Syrian crisis and the solution must be "political".
Urging the Security Council to assume its responsibilities, Guterres said a "lack of accountability" emboldens those who would use such chemical weapons by providing them with the "reassurance of impunity".
