NEW YORK: United Nations Secretary-General Antonio Guterres has condemned "in the strongest terms," the killing of dozens of civilians, including children and young people, by security forces in Myanmar on Saturday.

In a statement issued by Deputy Spokesman Farhan Haq, the UN chief  said, “the continuing military crackdown, is unacceptable and demands a firm, unified and resolute international response.

Meanwhile, acting leader of parallel civilian government in Myanmar, Mahn Win Khaing Than has stressed the need for formation of a federal coalition army to protect pro-democracy protesters from the coup-installed regime.

He said a federal coalition government would soon be formed following negotiations with political forces based in the country's ethnic areas.
