The strike comes after the United States and Germany recently authorized Ukraine to hit some targets on Russian soil with the long-range weapons they are supplying to Kyiv.

Under a new U.S. directive, Ukraine can use such weapons to strike across the border into Russia if forces there are attacking or preparing to attack.

The shutdowns were in place in all but three regions of Ukraine following Saturday’s drone and missile attack on energy targets that injured at least 19 people.
