The United Nations humanitarian aid chief Stephen O’Brien expressed serious concern after authorities in the eastern city of Luhansk called on UN agencies to immediately vacate the city.
“I am alarmed by news that the de facto authorities in eastern Ukraine have ordered UN agencies in Luhansk to end operations and to leave the area by tomorrow, 25 September,” said Mr O’Brien in a statement.
Mr Obrien added further concern at difficulties faced by NGOs attempting to set up office in Donetsk, reports Reuters.
Donetsk and Luhansk are both regions in eastern Ukraine controlled by pro-Russian separatist militants.
