The IAPB’s Tenth Progress Report presents the human rights situation in Belarus from 1 October 2025 to 30 March 2026 and outlines the Platform’s continued efforts to advance accountability and support survivors.

During the reporting period, repression in Belarus remained systematic and widespread, characterised by continued politically motivated prosecutions, widespread misuse of extremism and terrorism legislation, and expanding forms of transnational repression. At least 390 new instances of politically motivated persecution were documented, while the cumulative number of convictions since 2020 exceeded 8,200. As of March 2026, 911 individuals remained imprisoned for political reasons, despite large-scale pardons affecting 448 detainees—measures that largely reflected tactical or diplomatic considerations rather than genuine improvements in human rights conditions. Repression extended beyond imprisonment: released individuals faced deportation, surveillance, coercion, and restrictions on civil life.

Detention conditions continued to involve severe ill-treatment, including beatings, asphyxiation, and denial of medical care, with prolonged incommunicado detention and arbitrary sentence extensions further entrenching abuses.

The IAPB continued to expand its evidence base and analytical outputs. During the reporting period, it conducted 79 additional witness interviews, bringing its database to over 38,000 documents and more than 3,300 interview transcripts. Its open-source archive grew to over 2.19 million items, including extensive audiovisual and textual materials. The Platform further strengthened its linkage analysis to support attribution of responsibility to senior officials and to facilitate criminal case-building.

Cooperation with accountability mechanisms contributed to the decision of the Office of the Prosecutor of the International Criminal Court to open an investigation into crimes against humanity related to the Lithuania/Belarus situation. In the reporting period, the IAPB provided evidence to the ICC and to national authorities in two States, and shared over 3,000 files with the UN Group of Independent Experts. Overall, by March 2026, the Platform had contributed to 14 requests from national jurisdictions and multiple international mechanisms.

The IAPB also reinforced its survivor-centred approach. An additional 133 survivors received mental health and psychosocial support during the reporting period, bringing the total number of beneficiaries to 850. Particular attention was given to former political prisoners, who exhibit high levels of trauma, including PTSD and depression, and face significant reintegration challenges, especially in contexts of forced displacement.

Beyond documentation and support activities, the IAPB continued its advocacy, capacity-building, and coordination efforts, including the promotion of accountability pathways through its report “Paths to Accountability for Belarus,” engagement with international networks, and support for universal jurisdiction initiatives.

The IAPB remains a central actor in documenting violations, supporting survivors, and advancing justice and accountability for crimes committed in Belarus, and will continue its operations beyond the current project cycle (1 October 2023 to 30 September 2026).
