Forty percent of the Ukrainian population needs humanitarian aid, according to the same source.
But the country is now preparing to face the harshest winter, the Russian army having already destroyed a large part of its energy infrastructure, and continuing to do so.
During the previous two winters, millions of Ukrainians suffered regular power cuts, including heating cuts in temperatures below zero degrees Celsius.
Mr Schmale warned the situation was worse this year, with 65% of Ukraine’s energy capacity now destroyed.
He said he was in Geneva to call for more financing of specific aid of 500 million dollars (470 million euros) to help Ukraine get through the winter, which to date has only been provided by height of half.
The UN’s comprehensive humanitarian aid plan for Ukraine has so far helped more than seven million people, with funding of $1.8 billion (1.7 billion euros) out of a planned total of three billion.
