United Nations Secretary-General Antonio Guterres on Sunday called for "utmost restraint and a cessation of all military activities" in Yemen, his spokesperson said, after the United States launched deadly strikes in the country.
"Any additional escalation could exacerbate regional tensions, fuel cycles of retaliation that may further destabilize Yemen and the region, and pose grave risks to the already dire humanitarian situation in the country," UN spokesperson Stephane Dujarric said in a statement.
