Russia claimed Sunday that its forces are for the first time pushing into the central Ukrainian region of Dnipropetrovsk, an area it has been trying to reach for months, in a move that could create new problems for Kyiv’s much-stretched forces.

The Russian Ministry of Defense said soldiers have advanced into the Dnipropetrovsk region in south-central Ukraine.

The large-scale attack comes days after Trump says Putin had "very strongly" promised response to Ukraine "Spider web" attack.

At least seven people were killed and 41 others were injured in massive Russian strikes across Ukraine overnight, which targeted civilian and energy infrastructure.
