The UN Human Rights Council has voted in favor a resolution to set up an inquiry into alleged war crimes carried out by the Sri Lankan government.

Members of the 47-nation U.N. Human Rights Council have agreed to set up the yearlong investigation, estimated to cost $1.46 million, based on the recommendation of U.N. High Commissioner for Human Rights Navi Pillay, Associated Press reported.

By a 23-12 vote Thursday, with 12 abstentions, the council approved a U.S.-led resolution authorizing Pillay’s office to launch “a comprehensive investigation into alleged serious violations and abuses of human rights and related crimes by both parties in Sri Lanka.” The inquiry also seeks to hold perpetrators accountable.

Pillay earlier recommended that the 47-nation Human Rights Council authorize an investigation, saying Sri Lanka has made “little progress” toward ensuring accountability for alleged atrocities and war crimes committed during the civil war against minority Tamil rebels.
