Having been a central figure in the deciding stages of Eelam War IV, Jayasuriya has, like Sarath Fonseka and Gotabhaya Rajapakse, been accused of being complicit in the alleged war crimes carried out by the SLA during this period. On 28 August 2017, the International Truth and Justice Project (ITJP)- a group affiliated with the Foundation for Human Rights based in South Africa- filed lawsuits against Jayasuriya in Brazil and Colombia, citing his alleged complicity and command role in artillery strikes on hospitals and other civilian targets, torture (including sexual violence) and enforced disappearances. The same lawsuits were planned to be filed in Argentina, Chile and Peru, while Suriname had refused to accept them.
