"A total of 100 trucks delivered more than 1,100 tons of humanitarian aid to Donetsk," Oleg Voronov, deputy chief of the crisis management center with the Russian Emergencies Ministry, said.
Earlier in the day, Voronov said that 70 trucks delivered 700 tons of food products, construction materials, and other supplies required for the population's sustenance to Luhansk.
After being unloaded, the trucks will head back to Russia's southern region of Rostov.
The 14th convoy to Donbas will be sent on February 15, according to the ministry.
Ukrainian southeastern regions of Donetsk and Luhansk have been facing a severe humanitarian crisis since Kiev started a military operation against local independence supporters in April 2014.
Since August 2014, Russia has sent 12 convoys with over 16,000 tons of humanitarian aid to the region.
