联合国秘书长古铁雷斯的发言人发表声明说，秘书长“对叙利亚西南地区最近包括地面进攻和空中轰炸的军事行动升级十分关注”。
声明说：“攻击行动造成成千上万的平民流离失所，其中大部分人前往约旦边境地区。秘书长同时担心这些攻击行动对地区安全构成重大危险。”
古铁雷斯秘书长呼吁“立即停止军事行动升级，并敦促所有利益攸关者依照国际法和国际人道法履行他们的义务，包括保护平民和平民设施”。
约旦2017年7月协调达成了美国和俄罗斯在叙利亚南部实行停火的协议。
但是叙利亚政府没有同意这项降低冲突的协议，尽管它的盟友俄罗斯是协议签署方之一。叙利亚政府继续向反政府武装所在的地区投放传单，只给他们两个选择：投降或灭亡。
美国国务院6月早些时候的一份声明表示对叙利亚政府在西南地区军事行动升级感到关切，并警告说，叙利亚政府违反停火的行为将受到“坚决和适当措施”的回应，并称俄罗斯有责任让叙利亚政府遵守这项协议。
U.N. Secretary-General Antonio Guterres is “gravely concerned by the recent military escalation, including ground offensives and aerial bombardments, in southwestern Syria,” according to a statement from his spokesman.
“The attacks have resulted in the displacement of thousands of civilians, the majority of whom are moving towards the Jordanian border. The Secretary-general is also concerned at the significant risks these offensives pose to regional security, ” the statement says.
Guterres has called for “an immediate end to the current military escalation and urges all stakeholders to respect their obligations under international law and international humanitarian law, including the protection of civilians and civilian infrastructure.”
Jordan brokered a cease-fire agreement in southern Syria between the U.S. and Russia in July 2017.
But the Syrian government has not agreed to the de-escalation agreement, despite the fact that its ally, Russia, was a party to the deal. The Syrian government continues to drop leaflets in the area giving armed opposition two choices — surrender or die.
The U.S. State Department issued a statement earlier this month expressing its concerns about the escalation by the Syrian government in the southwest, warning of “firm and appropriate measures” against the Syrian government’s violation of a cease-fire, and holding Russia responsible to compel the Syrian government to the agreement.
