"A total of 80 trucks delivered food items and other daily essentials to Donetsk," Oleg Voronov, deputy chief of the crisis management center with the Russian Emergencies Ministry, told RIA Novosti.
Earlier in the day, Voronov said that the same number of trucks carrying humanitarian aid had arrived in the Luhansk region.
Ukraine's southeastern regions of Donetsk and Luhansk have been suffering from a severe humanitarian crisis since Kiev launched a military operation against local independence supporters in April 2014. Thousands of people lost their homes and crucial infrastructure has been damaged.
Since August 2014, Russia has sent over 20,000 tons of food, water, clothes, medicines, power generators and building materials to the Donetsk and Luhansk self-proclaimed republics.
