Eastern Ukraine: Saber-rattling between Moscow and Kyiv

In the first week of April, Russia had begun to build up its military presence at the border with Ukraine. This was a reaction to Ukraine's "provocations" — which were aimed at escalating the conflict between Russian separatists and Ukrainian government troops, the Kremlin said. According to observers sent by the Organization for Security and Cooperation in Europe (OSCE), there was no provocation.

The US, NATO and the EU have pledged support for Ukraine's efforts to defend its territory. Ankara said on Friday that the US had already announced at the end of March that it would be sending two warships to the Black Sea in mid-April. The USS Thomas Hudner (pictured) is one of two missile destroyers which sailed through the Bosporus in March.

The conflict in eastern Ukraine broke out in early 2014, when pro-Russian rebels seized control in parts of the Ukrainian districts of Donetsk and Luhansk. According to the Ukrainian government and its Western allies, the Kremlin supports the rebels unofficially by providing mercenaries and weapons. Since 2014, several ceasefires have been agreed upon. They were, however, broken time and again.

Although mainly soldiers, mercenaries, rebels and militiamen are involved in the conflict, the civilian population is repeatedly affected. At the beginning of 2019, the UN recorded 3,300 civilians killed.

Since 2014, combat activities of varying intensity have claimed the lives of a total of more than 13,000 people. The current ceasefire, in force since July 2020, is relatively stable, according to the OSCE. Recently, however, hostilities have increased again. At least seven Ukrainian government soldiers and a five-year-old boy were killed during the last two weeks.

During a visit to the Donbass region earlier in the week, Ukrainian President Volodymyr Zelenskiy inspected the situation on the ground and honored soldiers for services rendered. On Saturday, he will meet President Recep Tayyip Erdogan in Turkey. According to Ukrainian media reports, a meeting with French President Emmanuel Macron is on the agenda as well.

By international law, the renegade areas belong to Ukraine. However, some 400,000 residents with Russian citizenship inhabit the zone. "To protect them," Moscow announced on Friday, the Kremlin would take action. White House Press Secretary Jen Psaki, meanwhile, said that "Russia now has more troops on the border with Ukraine than at any time since 2014."
