LAGOS, Nigeria — Nigeria’s Boko Haram Islamic extremists have a new leader who promises to end attacks on mosques and markets used by Muslims, according to an interview published Wednesday by the Islamic State group.

The group’s al-Nabaa newspaper identified Abu Musab al-Barnawi as the new ‘‘Wali’’ of its West Africa Province, a title previously used to describe long-time leader Abubakar Shekau.

The report did not say what Shekau’s current status is.

The interview with Barnawi indicates a major change in strategy for the Nigerian extremists, who have attacked mosques with suicide bombers and gunmen, blown up suicide bombers in crowded marketplaces, and killed and kidnapped schoolchildren. The targeting of students accounts for its nickname Boko Haram, which means Western education is sinful or forbidden.

Wednesday’s announcement indicates a coup by Boko Haram breakaway group Ansaru against Shekau, and follows a trend of extremist Islamic groups moving away from Al Qaeda to the Islamic State, analyst Jacob Zenn said.

Ansaru broke away from Boko Haram because it disagrees with the indiscriminate killing of civilians, especially Muslims.

Barnawi is the pseudonym of a Nigerian journalist allied with Ansaru, which is known for kidnapping foreigners, according to Zenn.

Shekau in March 2015 declared that Boko Haram had become the Islamic State’s West Africa province. At the time, Boko Haram was the most powerful military force in northeast Nigeria, controlling a huge area and better equipped and motivated than Nigerian forces.

Under Shekau, the seven-year insurgency spread to neighboring countries, killed more than 20,000 people and drove more than 2.2 million from their homes.
