More than 100 Ukrainian drones were shot down over Russia Sunday, Russian officials said, sparking a wildfire and setting an apartment block alight in one of the largest barrages seen over Russian skies since Moscow invaded Ukraine in February 2022.

Ukrainian President Volodymyr Zelensky said in February that Kyiv would create a new branch of Kyiv's military, known as the Unmanned Systems Forces, dedicated exclusively to drone warfare. "Drones, unmanned systems, have proven their effectiveness in battles on land, in the sky and at sea," the Ukrainian leader said.
