Ukraine fired cluster munitions at a Russian village near the Ukrainian border on Tuesday, causing damage to several homes, the governor of the Russian Bryansk region, Alexander Bogomaz, said.
Bogomaz added on Telegram that preliminary information indicates that there were no casualties as a result of the bombing that targeted the village of Klimovo.
Ukraine received cluster munitions from the United States, but pledged to use them only to expel concentrations of enemy soldiers.
Russian officials in Bryansk and other regions bordering Ukraine have often said that the Ukrainian armed forces are bombing these areas indiscriminately.
More than 100 countries ban the use of cluster munitions.
Cluster munitions usually release a large number of small bombs to randomly kill people over a large area.
Small bombs that do not explode pose a danger that lasts for years.
