Russia on Wednesday reiterated the need to create humanitarian corridors in southeastern Ukraine, where clashes between governmental troops and separatists saw no ease.

"There is a growing amount of evidence that Ukrainian authorities hamper movement of people to Russia. There is a growing number of such cases and this is alarming for us very much," Russian presidential administration chief Sergei Ivanov told reporters in the Siberian city of Novosibirsk.

Noting that the issue of humanitarian corridors was becoming increasingly topical, Ivanov said he had asked Russia's Rostov-on-Don region to prepare for the arrival of refugees from Ukraine.

"The whole network of sanatoria and holiday homes was already created there, prepared to receive Ukrainian citizens in worthy conditions as the latter need protection and salvation," Itar-Tass news agency quoted him as saying.

Ivanov added that similar centers for accommodating refugees would be created in Russia's Voronezh, Bryansk and Belgorod regions.

Russia on Monday submitted a draft resolution on Ukraine to the UN Security Council, proposing to create humanitarian corridors to allow civilians to leave voluntarily.

Russian Deputy Foreign Minister Gennady Gatilov said Wednesday that the West did not support the initiative "as they consider that there are no humanitarian problems in eastern Ukraine."

Russia has repeatedly said a humanitarian catastrophe was haunting Ukraine, while Kiev has accused Moscow of inciting unrest in its southeastern regions.
