UNITED NATIONS－The United Nations announced on Thursday it is immediately allocating $20 million to scale up UN humanitarian operations in Ukraine.

UN humanitarian chief Martin Griffiths said the $20 million from the UN's Central Emergency Response Fund will support emergency operations along the contact line in eastern Donetsk and Luhansk and in other areas of the country, and will "help with healthcare, shelter, food, and water and sanitation to the most vulnerable people affected by the conflict".

David Beasley, executive director of the UN World Food Program, expressed deep concern at the potential impact of the conflict on access to food for civilians in conflict areas.
