US attack in Iran a 'threat' to international peace: UN

UN Secretary-General Antonio Guterres said he was gravely alarmed by the use of force by the US against Iran, and called it a "direct threat to international peace and security.

The US strikes in Iran are a "dangerous escalation in a region already on the edge," and urged for de-escalation in a statement.

"There is a growing risk that this conflict could rapidly get out of control – with catastrophic consequences for civilians, the region, and the world," Guterres said.

"At this perilous hour, it is critical to avoid a spiral of chaos," Guterres said in his statement. "There is no military solution. The only path forward is diplomacy.  The only hope is peace."
