One person was killed in a Ukrainian attack on Russian-occupied Crimea, Moscow-installed officials said in the early hours of Sunday, as Russian and Ukrainian leaders held separate calls with U.S. President Donald Trump on ending the war, now in its fifth year.

Two others were injured in the attack on northern Crimea, including one in a serious condition, the Russia-installed regional Gov. Sergei Aksyonov wrote on Telegram. He did not give details of the attack.
