Three Ukrainians were killed in Donbas on May 11 and violations of the ceasefire regime by the militants were ongoing, Ukrainian Foreign Minister Pavlo Klimkin said on Tuesday.

"We are observing constant ceasefire violations. Three Ukrainians were killed and another few were injured just yesterday," he said at a roundtable titled "Humanitarian Aid by International Organizations and Donor States: How the Host Country's Government Can Help" in Kyiv on Tuesday.
