A 50-year-old man was killed in an explosion caused by a cluster submunition in Kharkiv Oblast's village of Ivanivka near Izium, Governor Oleh Syniehubov reported on March 22.
Ukrainian forces liberated Izium and most of Kharkiv Oblast in September after about six months of Russian occupation.
Over 100 countries ban cluster munition use, but Russia continues to use the weapons – which release small explosive bombs and indiscriminately harm civilians. Russia is not a signatory of the 2008 convention, but it is obliged by international humanitarian law to avoid its use.
Another civilian stepped on a Russian landmine in a forest next to the village of Velyka Oleksandrivka in southern Kherson Oblast, according to the regional administration.
As a result of the explosion, the 48-year-old man "lost part of his leg" and was hospitalized, the administration said.
The village of Velyka Oleksandrivka is located on the west bank of the Dnipro River in Kherson Oblast. Russian forces were pushed to the river's east bank when Ukraine liberated Kherson in November 2022, from where they had been firing at the liberated territories.
Local authorities of Kherson and Kharkiv oblasts urged residents to avoid fields, forests, riverbanks, and other places that have not yet been examined by sappers.
According to Interior Minister Ihor Klymenko, nearly one-third of Ukraine, including liberated and occupied territories, remains mined as of March 1.
