The small incursion targets the Belgorod region, according to Ukrainian officials, analysts of open-source intelligence and Russian military bloggers. The advance comes as cease-fire talks continue.

"Russian President Vladimir Putin has agreed to a 30-day energy and infrastructure ceasefire," writes Kyiv Post. Ukrainian media are commenting on a statement made by the Kremlin's spokesperson. Dmitry Peskov stated that Russia reserves the right not to adhere to the ceasefire in Ukraine if it is violated.

Russia reserves the right not to honour a moratorium on strikes against energy facilities should Kyiv breach it. Anything else would be illogical — stated the Kremlin spokesman on Friday. Dmitry Peskov simultaneously accused Ukraine of carrying out attacks on facilities within Russia.
