President Trump held separate calls with Russian President Vladimir Putin and Ukrainian President Volodymyr Zelenskyy on Sunday to discuss ending the war in Ukraine, which is now in its fifth year. The calls took place as a Ukrainian attack on Crimea left one person dead, according to officials installed by Moscow in the Russian-occupied territory.Two people were also injured, one seriously, in the attack in northern Crimea, said the Russian-installed regional Gov. Sergei Aksyonov on Telegram. Aksyonov did not provide details about the attack.In recent weeks, Ukraine has stepped up its attacks on key infrastructure targets in Crimea as Kyiv's military seeks to isolate the vital Russian-held peninsula in the latest stage of the war. Russian authorities in Crimea announced a state of emergency in the area at the end of last month, which halted all fuel sales to civilians in response to Ukrainian attacks. Putin, in a rare admission, told a Russian journalist around that time that the Ukrainian strikes were causing "problems" for Russia.Crimea was seized by force and illegally annexed by Moscow in 2014. Ukraine's increasing use of long-range strikes has highlighted its ability to inflict painful damage on Russia and put added pressure on the Kremlin while Moscow's advances recently have ground to a near halt, Western analysts and officials say.The latest attacks came after Zelenskyy and Putin spoke with Mr. Trump about ending the war.
