Russia's Acting Minister of Emergency Situations, Aleksandr Chupriyan, said that the ministry has sent 18 convoys of humanitarian aid shipments to Donbass, according to RT.

Chupriyan said that these materials will be distributed to refugees and local residents residing in the liberated areas of the Lugansk and Donetsk People's Republics.

"I must say that the Russian Emergencies Ministry has already sent 18 humanitarian aid convoys there," the acting minister said.

"In fact, we have three centers for coordinating the distribution of humanitarian aid - in Rostov, Crimea and Belgorod province,” the Russian official continued according to reports from RT.

On the other hand, a fourth round of negotiations between Moscow and Kyiv began on Monday, according to what a senior Ukrainian official announced, in light of the exchange of accusations of bombing and the killing of civilians earlier on Monday.

The head of the negotiating delegation for Kyiv and aide to the Ukrainian president, Mykhailo Podolyak, posted on Twitter a photo of video chats with Russian officials, describing the negotiations as "difficult" and noting that the two sides reviewed their "specific positions."

He believed that "the reason for [their] differences is that [they] have two very different political systems."

This is the fourth round of talks between Podolyak and his Russian counterpart Vladimir Medinsky, a Kremlin adviser.
