At least three people were killed and dozens of houses were damaged by explosions in Russia's city of Belgorod near the Ukrainian border.

Governor Belgorod Vyacheslav Gladkov said that in addition to casualties, at least 11 apartment buildings and 39 houses were damaged.

We are trying to determine the situation.

Two of the victims were injured, one man and one child, was hospitalized, the other two were treated on the spot, he said.

Russian parliamentary Andrrei Kishas accused Ukraine on Belgorod shelling of Belgorod causing explosions and calling for a strict response from the government.

The photo posted by Governor Gladkov showed a house damaged by explosions on July 3.

Causing casualties for civilians and destroying civil infrastructure in Belgorod is a direct aggression of Ukraine and requires the most serious response, including military action,

Since the conflict broke out in February, Moscow has accused Kiev behind a number of attacks on Belgorod, the city with more than 400,000 people about 40 km north of Ukraine, and other areas of the armor.

Kiev did not take responsibility but described these attacks as the price paid for Moscow's actions.

Kiev has not commented on the latest series of explosions that occurred in Belgorod.
