"We are coping, and I have no doubt that we will cope," said Russia's foreign minister, Sergey Lavrov.

That included a Monday joint statement from Republican Sen. Lindsey Graham and Democratic Sen. Richard Blumenthal calling Trump’s threat of ramped-up economic penalties if Russia doesn’t cut a peace deal in next 50 days “a real executive hammer to drive the parties to the negotiating table.”

Ukraine's air force said Russia targeted several regions overnight with 267 drones, of which around 200 were Shahed attack drones and the rest decoys. The air force said it shot down or otherwise suppressed 244 drones. Twenty-three drones impacted across seven locations, with falling debris reported in nine locations, the air force said.
