JOHANNESBURG (AP) -- The U.S. military has switched from trying to degrade Islamic extremist groups in West Africa's sprawling Sahel region to merely trying to contain them as their deadly threat increases, a new U.S. government report says.
The quarterly report by the inspectors general for the Pentagon, State Department and USAID released this week is the first to be unclassified as interest surges in the U.S. military's activities in Africa. Security allies are worried as the U.S. considers cutting troops on the continent to counter China and Russia elsewhere in the world.
Top concerns in Africa include the fast-growing threat from multiple extremist groups in the Sahel region just south of the Sahara Desert and the enduring threat by the al-Qaida-linked al-Shabab in Somalia, which killed three Americans in an unprecedented attack against U.S. forces in Kenya last month.
Consistent pressure on extremist groups is needed to weaken them, the report says, citing Defense Secretary Mark Esper, who has compared it to "mowing the lawn." That need, along with the often slow development of local partners' militaries, "could require ongoing commitment of U.S. military resources," the report adds.
The new report also says the U.S. Africa Command has expressed concerns to the Pentagon's inspector general that some resources will be moved from Somalia to the North African nation of Libya, where a conflict between rival governments has drawn the attention of powers including Russia and Turkey.
About 6,000 U.S. military personnel are deployed across Africa, the report says, including 500 special operations forces in Somalia and about 800 personnel in West Africa.
The security situation in Burkina Faso "is deteriorating faster than anywhere else in the Sahel," says the new report, citing AFRICOM. The West African nation is staggering under a growing number of extremist attacks as fighters move in from neighboring Mali. Hundreds of civilians have been killed and hundreds of thousands have fled.
Extremist groups linked to the Islamic State group and al-Qaida in West Africa "are neither degraded nor contained," the new report warns, citing AFRICOM.
The new U.S. military strategy has changed from trying to degrade, or reduce the effectiveness, of those extremist groups in the Sahel to trying to keep them from growing their membership and spreading into new areas, AFRICOM told the Pentagon inspector general in the quarter ending Dec. 31.
Mali's president this week told French media outlets his government is now in contact with leaders of the most active extremist group, the al-Qaida-linked JNIM, a sign that troubled West African countries are exploring various options, including negotiations, to curb the threat.
JNIM has about 1,000 to 2,000 fighters and its goal is to "unite all terrorist groups in the Sahel and eliminate Western influence in the region," the new U.S. report says.
The U.S. military in the Sahel largely supports the militaries of France and local countries in their fight against the extremists.
France recently announced it would increase its troop presence there to more than 5,000 and has started arming its drones, while French leaders have urged the U.S. against cutting its military presence.
