Sokoto, Nigeria. Armed extremists killed at least 162 people during attacks on two villages in western Nigeria, a lawmaker said Wednesday, in one of the deadliest assaults in recent months.

The attacks targeted the villages of Woro and Nuku in the state of Kwara on Tuesday evening, Mohammed Omar Bio, a member of parliament representing the area, told The Associated Press.

He said the attacks were carried out by the Lakurawa, an armed group affiliated with the Islamic State group.

A Red Cross official said earlier Wednesday that “scores of people were killed.” Ayodeji Emmanuel Babaomo, the Red Cross secretary in Kwara state, said the organization has been unable to reach the communities because they are in a remote area — about eight hours from the state capital and near Nigeria's border with Benin.

Governor AbdulRahman AbdulRazaq said in a statement released Wednesday that the attack was a “cowardly expression of frustration by terrorist cells” in response to ongoing military operations against armed extremists in the state. He did not provide a figure for the number of people killed. State police did not comment.

Nigeria is in the grip of a complex security crisis, with an insurgency by Islamic militants in the northeast alongside a surge in kidnappings for ransom by gunmen across the northwest and north-central regions over recent months.

In a separate attack on Tuesday, gunmen killed at least 13 people in the village of Doma in the northwestern state of Katsina, police spokesman Abubakar Sadiq Aliyu said in a statement Wednesday.

Investigations were underway to determine the circumstances and identify those responsible, he added.

Last week, armed extremists in northeastern Nigeria killed at least 36 people during separate attacks on a construction site and on an army base.

On Tuesday, the head of US Africa Command said the United States had sent a small team of military officers to Nigeria, the latest step in its response to the security crisis. In December, US forces launched airstrikes on IS-affiliated militants in Nigeria.

Africa’s most populous country has been in the diplomatic crosshairs of the U.S. following threats by President Donald Trump to attack the country, alleging it is not doing enough to protect its Christian citizens.

The armed groups in Nigeria include at least two affiliated with IS, an offshoot of the Boko Haram extremist group known as the Islamic State West Africa Province in the northeast, and the lesser-known Islamic State Sahel Province (ISSP), known locally as Lakurawa, and prominent in the northwest.

The Nigerian military has said in the past that the Lakurawa has roots in neighboring Niger and that it became more active in Nigeria’s border communities following a 2023 military coup.
