Five human rights experts with the United Nations have sent a letter to the Nigerian government warning that the country’s recent blasphemy laws may be in violation of international human rights laws, the Christian Post reports.

The letter focussed primarily on what has happened recently to two Christian women, Deborah Emmanuel Yakubu and Rhoda Jatu.

In 2022, Yakubu was killed when a mob of Muslim students at Sokoto State University set her on fire after she shared a social media post thanking Jesus for helping her pass an exam.

Jatau, who is the mother of five children, has been in prison ever since she shared a video criticizing the senseless murder of Yakubu.

Jatau has been denied bail several times since her trial started in December 2022. Both Christian women were accused of blasphemy.

In the letter sent by U.N. special rapporteurs Morris Tidball-Binz, Nazila Ghanea, Irene Khan, Matthew Gillett and Fernand de Varennes, the group stated that both the killing and the arrest “appear to be related to the legitimate exercise of the right to freedom of thought, conscience and religion and of freedom of opinion and expression.”

Nigeria has a population of 230 million people. Just over 50% are Muslim, who are increasingly dominating the country’s political landscape.
