The United Nations special rapporteur on extrajudicial killings condemned rising violence across Nigeria and a “lack of accountability” for perpetrators.
Agnes Callamard, speaking at a news conference on Monday in Abuja, said the country needed urgent action to end the “pressure cooker” of violence that has claimed thousands of lives.
Nigeria is currently facing multiple conflicts, from attacks by the armed group Boko Haram to fighting between nomadic herders and farmers.
“The overall situation that I encountered in Nigeria gives rise to extreme concern … The warning signs are flashing bright red: increased numbers of attacks and killings over the last five years with a few notable exceptions,”Callamard said at a news conference.
“If ignored its ripple effect will spread throughout the sub-region given the countrys important role in the continent.”
She condemned police and military “brutality” across the country, and a “generalised system of impunity”.
“The time is now to prioritise the rule of law and to make it part and parcel of the Nigerian system,” especially for those living in extreme poverty, she said.
Cheta Nwanze, an analyst at SBM Intelligence, told Al Jazeera: “In almost two decades of Boko Harams existence, I cant recall any of the financial backers who has ever been brought to trial … Weve not had a single high-level conviction of a Boko Haram member.”
The United Nations estimates more than 27,000 people have been killed and an estimated two million others displaced in Nigerias northeast alone because of Boko Haram.
Callamard has been in Nigeria since August 16and investigated the scope of violence in the country. She has also assessed measures adopted by the government to tackle the killings.
In Nigerias central states, clashes between farmers and nomadic herders over dwindling arable land have killed thousands of people and displaced tens of thousands of others.
“Nigeria is a pressure cooker of internal conflict. The absence of accountability is on such a scale that pretending this is not a crisis will be a major mistake,” said Callamard.
“The increased number of people living in absolute poverty, climate change and desertification, and the increased proliferation of weapons, altogether, these are reinforcing a localised system of violence,” she added.
The UN special rapporteur also examined safeguards over the use of the death penaltyand laws applied by Islamic courts.
“I have also considered security repression against Shia Muslims, the indigenous people of Biafra, and against Ogoni people,”Callamard said.
She noted there had been key decisions made by courts but added, “these are not being implemented. I am hoping that the government will hear my call and demand that court orders are implemented”.
