Russia on Tuesday said its military would do everything possible to stop the Ukrainian shelling of Belgorod, a border town where hundreds were evacuated after fatal bombardments.
The pledge came as Defence Minister Sergei Shoigu said Russian forces were dictating the course of fighting on the front line, which has barely shifted in about a year despite fierce fighting.
Belgorod has suffered an uptick in fatal shelling attacks in recent weeks that prompted city officials to recently evacuate hundreds and extend a closure of schools.
"Of course, our military will continue to do everything in order to minimise the danger at first and then eliminate it entirely," Kremlin spokesman Dmitry Peskov told reporters.
He accused the Ukrainian military of firing on civilian targets in the centre of the urban hub of some 340,000 people with weapons supplied by European countries.
The Kremlin has tried to maintain a semblance of normalcy on the home front, but the recent strikes on Belgorod have brought the Ukraine conflict closer to home for Russians.
A bout of aerial attacks from Kyiv's forces in Belgorod last month killed 25 people -- the worst attack on Russian civilians since the conflict began nearly two years ago.
- 'Strategic initiative' on front -
The head of the region, Vyacheslav Gladkov, on Tuesday said three people had been injured by debris from downed Ukrainian weapons.
He said Russian air defence systems in the city had repelled 10 attacks overnight, leaving several homes damaged.
City officials last week encouraged residents to place tape over their windows to stop them from shattering during strikes, a measure widespread across Ukraine.
Even though the front line in Ukraine is largely static, Shoigu on Tuesday assured Russian defence officials that his forces were in control.
"We retain the strategic initiative along the entire line of contact," he said, accusing the United States of pressuring Ukraine to keep fighting against Russia.
Western backing for Ukraine, Shoigu said, would not change the outcome but only prolong fighting.
He also said Russia would step up production of drones -- a weapon increasingly used by both the Ukrainian and Russian militaries -- this year.
Separately, Ukrainian authorities said the death toll from a Russian strike in the west of the country a day earlier had risen to three.
"Unfortunately, as a result of rescue operations, one more fatality was found -– a man born in 1955. Sincere condolences to the family," Khmelnytskyi mayor Oleksandr Symchyshyn said on social media.
The attacks in the western region came as part of a country-wide barrage that left at least five people dead and dozens more injured.
