The U.S. Africa Command said on Monday it had carried out additional ​airstrikes against Islamic State targets in northeastern Nigeria on ‌Sunday, in coordination with the Nigerian government, as joint operations against militant groups intensify.

Nigeria’s Defence Headquarters said the latest strikes were conducted in ​the Metele area of Borno State, following intelligence that ​fighters had converged there.

Multiple airstrikes killed more than 20 ⁠Islamic State West Africa Province (ISWAP) militants, according to a ​statement.

AFRICOM said no U.S. or Nigerian personnel were harmed in the ​operation.

The strikes come a day after a joint U.S.-Nigerian mission that killed Abu-Bilal al-Minuki, described by both governments as the second in command of Islamic ​State globally.

U.S. President Donald Trump and Nigerian President Bola Ahmed ​Tinubu confirmed the development, describing it as a major setback for the ‌militant ⁠group.

Tinubu said Nigerian forces worked closely with the U.S. military in what he called a daring joint operation that dealt a heavy blow to Islamic State’s leadership.

Trump, who has previously criticised ​Nigeria over security ​issues, thanked ⁠the Nigerian government for its cooperation.

Nigeria’s military said the latest operations formed part of sustained efforts ​to disrupt insurgent networks, remove fighters from the ​battlefield ⁠and deny them safe haven.

Borno State, in Nigeria’s northeast, has endured a 17-year insurgency led by Boko Haram and its splinter ⁠group ISWAP. ​The conflict has killed thousands and ​displaced about 2 million people.
