submitted a document to the Mine Ban Treaty Third Review Conference, stating that it has destroyed 568,248 mines since the ratification, with an additional 576 mines in 2014, leaving its stockpile at 5,434,672 mines. After failing to adhere to the Ottawa treaty deadline of November 2018 on the destruction of its anti-personnel mines, Ukraine requested the deadline be extended til 1 June 2021, later asking for further extension on 8 June 2020. The effort for the destruction fizzled out towards 2019 and 2020, with only 67,236 destroyed in 2019. In 2020, Ukraine refused to destroy any PFM-1 mines. In 2021, Ukraine's PFM-1 stockpile is reported at 3,363,828 mines, with no further submissions of their destruction. Military use Afghanistan PFM-1 was used during the Soviet Invasion of Afghanistan, allegedly resulting in a high number of casualties among children from being mistaken for a toy due to its shape and coloring. Ukraine The Ukrainian state declared that the Russian Federation deployed PFM-1 mines during the 2022 Russian invasion of Ukraine. In March 2022, Deutsche Welle found no evidence to support this accusation. In June, Human Rights Watch reported that Russia had used "at least seven types of antipersonnel mines in at least four regions of Ukraine: Donetsk, Kharkiv, Kyiv, and Sumy", but could not ascertain PFM-1 use in its briefing. HRW found no credible information about Ukraine using any anti-personnel mines, but said in January 2023 that its team "saw physical evidence of PMF antipersonnel mine use in seven of the nine areas around Izyum" in Kharkiv Oblast, and urged the Ukrainian government to investigate possible PMF use by its forces. In Russian-controlled Donetsk, many PFM-1 were dispersed widely, and Russian and local sources accused the Ukrainian army of being responsible for their deployment. There have been reported casualties, most prominently Semen Pegov, a Russian war blogger calling himself "War Gonzo". Similar weapons The PFM-1 is very similar to the BLU-43 landmine used by the US Army in Operation Igloo White in Laos during the Vietnam War. According to a U.S. military document, the Soviet military created PFM-1 after reverse-engineering BLU-43.
