PRYLUKY, Ukraine (AP) — At least five people, including a 1-year-old child, his mother and grandmother, were killed Thursday in a nighttime Russian drone attack on the northern Ukrainian city of Pryluky, officials said.

Following his talk with Putin, Trump expressed understanding for Russia’s need to retaliate against Ukraine’s drone strike against its bomber fleet.

At least five people were killed, including a child, and more than two dozen injured after Russian forces launched more than 100 drones, guided bombs and missiles at regions all across Ukraine overnight.

The Ukrainian operation was “grounds for a nuclear attack,” declared Vladmir Solovyov, a firebrand host on Russian state TV, calling for strikes on the Ukrainian presidential office in Kyiv, and beyond.

Rachel Maddow explains how Ukraine's "Spiderweb" drone operation, which destroyed several Russian military planes, exposed a huge global nuclear vulnerability.
