Russian airstrikes killed two people in Ukraine overnight, Ukrainian officials said Tuesday, as Russia's Defense Ministry reported that several Ukrainian drones targeted Moscow.

The attacks came as Ukrainian President Volodymyr Zelenskyy prepared to meet Donald Trump in New York.

The U.S. president is expressing mounting frustration at Russia for not halting its invasion.

Russia launched three missiles and 115 drones at Ukraine overnight, Kyiv's air force said, the latest in what are daily barrages.

Most drones were intercepted by air defense, but officials said one civilian was killed in the southern Zaporizhzhia region and another in the coastal Odesa region.

"Russia continued its terror against the people of Ukraine, targeting the civilian population in multiple regions of the country," Prime Minister Yulia Svyrydenko said on social media.

She renewed calls for Kyiv's allies to send more air defence systems.

"Every delay in strengthening Ukraine's air defense means more lives lost," she said.

Kyiv has stepped up its own wave of retaliatory long-range drone strikes on Russia.

Russia's Defense Ministry said it destroyed 69 Ukrainian drones over its territory, with no damage reported.

Over a dozen had targeted the capital Moscow, Mayor Sergei Sobyanin said on social media.
