HRW said Ukraine's launch of thousands of PFM-1 'petal' or 'butterfly' mines resulted in 11 verified civilian casualties, including one death and multiple lower leg amputations.
"These antipersonnel mines have had immediate and devastating consequences for civilians in and around Izium, including by tearing off limbs of residents as they go about their daily lives," Ida Sawyer, the director of HRW's crisis and conflict division, toldThe Washington Post on Friday.
The Ukrainian government has vowed to investigate the military's use of such inherently indiscriminate weapons that are banned under the 1997 Mine Ban Treaty, to which Ukraine is a signatory.
"Ukraine, exercising its right to self-defense in accordance with Article 51 of the U.N. Charter, fully implements its international obligations while Russian occupants commit war crimes, crimes against humanity, and genocide of the Ukrainian people," the Ukrainian Foreign Ministry said.
Unlike Ukraine, Russia is not bound by the Mine Ban Treaty. HRW says Russian forces have "used at least 13 types of antipersonnel mines in multiple areas across Ukraine, killing and injuring civilians."
HRW arms director Steve Goose said Friday that "the Ukrainian government's pledge to investigate its military's apparent use of banned antipersonnel mines is an important recognition of its duty to protect civilians."
"A prompt, transparent, and thorough inquiry could have far-reaching benefits for Ukrainians." he added, "both now and for future generations."
