UNITED NATIONS, March 2 (Aljazeera) - More than one million refugees have now fled Ukraine since Russia invaded the country, according to the UN refugee agency’s chief.

“In just seven days we have witnessed the exodus of one million refugees from Ukraine to neighbouring countries,” UN High Commissioner for Refugees Filippo Grandi, said in a Twitter post.

“For many millions more, inside Ukraine, it’s time for guns to fall silent, so that life-saving humanitarian assistance can be provided.”
