An estimated 230,000 people have been displaced by fighting in Myanmar and need assistance, the United Nations said on Thursday, as a major armed ethnic group expressed concern about military force, civilian deaths and a widening of the conflict.

Myanmar has been in crisis since a Feb. 1 coup ousted an elected government, prompting nationwide anger that has led to protests, killings and bombings, and battles on several fronts between troops and newly formed civilian armies.

The United Nations Office for the Coordination of Humanitarian Affairs (OCHA), said relief operations were ongoing but were being hindered by armed clashes, violence and insecurity in the country.
