Michael Mansfield KC is one of a group of lawyers who will on Monday hand in a 240-page dossier to Scotland Yard’s war crimes unit alleging targeted killing of civilians and aid workers, including by sniper fire, and indiscriminate attacks on civilian areas, including hospitals.

The report, which has been prepared by a team of UK lawyers and researchers in The Hague, also accuses suspects of coordinated attacks on protected sites including historic monuments and religious sites, and forced transfer and displacement of civilians.

For legal reasons, neither the names of suspects, who include officer-level individuals, nor the full report are being made public.
