Another "humanitarian aid convoy" from Russia has arrived in Ukraine in violation of international agreements, National Security and Defense Council (NSDC) spokesman Andriy Lysenko has said.

"Today, from 07.25 to 07.45, the Russian side, violating international and intergovernmental agreements and without informing the Ukrainian side, moved to Ukraine ten trucks of another so-called 'humanitarian convoy' at the Donetsk checkpoint in Russia," he said at a briefing in Kyiv on Tuesday.
