United Nations Secretary-General Antonio Guterres condemned in the strongest terms the killing of dozens of civilians, including children and young people by security forces in Myanmar.
Guterres made the remarks in a statement on Saturday.
He also said "the continuing military crackdown, which resulted in the highest daily death toll since demonstrations against the coup began last month, is unacceptable."
He demanded "a firm, unified and resolute international response" and added that "it is critical to find an urgent solution to this crisis."
The UN chief reiterated his urgent appeal to the military "to refrain from violence and repression." He continued, "Those responsible for the serious human rights violations must be held accountable."
