Unidentified gunmen attacked eight villages in the northwestern Nigerian state of Kebbi, killing at least 88 civilians.

Iran Press/Africa: Nigerian police said the attacks took place on Thursday, but details and news were released on Sunday.

The governor of Kebbi, Abu Bakr Bagudu, said on Sunday that the attackers had come to Kebbi from Niger and Zamfara provinces and that they had destroyed livestock and agricultural products in the eight villages.

No group has claimed responsibility for the attacks, but it is likely that the Boko Haram terrorist group is behind them.

Meanwhile, the ISIS terrorist group announced on Sunday night the death of Abubakar Shekau, the leader of the Boko Haram terrorist group in Nigeria.

Abu Musab al-Bernawi, the leader of ISIS in West Africa, said in an audio file that Abubakar Shekau was killed around May 18 (last month) shortly after an explosive device exploded while being pursued by ISIS.

The Boko Haram terrorist group took up arms in 2009 with the aim of establishing itself in northern Nigeria and expanded its attacks to Niger, Chad and northern Cameroon.

Boko Haram has killed more than 30,000 people in Nigeria, Cameroon, Niger and Chad during this period and displaced more than two million.
