Sierra Leone said attacks on several locations in the capital Freetown on Sunday were a failed attempt to overthrow the government.
More than 20 people, including 14 loyalist soldiers, were killed in the attacks. Thirteen military officers and one civilian have been arrested following the incident.
There have been eight military coups in West and Central Africa since 2020.
Here is a list of some recent coups:
GABON
In August, military officers in oil-producing Gabon said they had seized power, placing President Ali Bongo under house arrest. They named General Brice Oligui Nguema, former head of the presidential guard, as the new leader after election body announced Bongo had won a third term.
The junta has said that it aimed to hold elections in August 2025, two years after the military coup.
NIGER
In July 2023, members of Niger's presidential guard detained President Mohamed Bazoum inside his palace and appeared on national television saying they were seizing power to end the "deteriorating security situation and bad governance".
Days later the junta declared the head of the presidential guard, Abdourahamane Tiani, the new head of state, raising concerns about the security of a region where Niger has been a key ally of Western powers seeking to contain insurgencies by groups linked to al Qaeda and Islamic State.
The main West African bloc ECOWAS has been trying to negotiate with the coup leaders but said it was ready to send troops into Niger to restore constitutional order if diplomatic efforts failed.
BURKINA FASO
In January 2022, Burkina Faso's army ousted President Roch Kabore, blaming him for failing to contain violence by Islamist militants.
Coup leader Lieutenant Colonel Paul-Henri Damiba pledged to restore security, but attacks worsened, eroding morale in the armed forces that led to a second coup in September 2022 when current junta leader Captain Ibrahim Traore seized power.
GUINEA
In September 2021, special forces commander Colonel Mamady Doumbouya ousted President Alpha Conde. A year earlier, Conde had changed the constitution to circumvent limits that would have prevented him from standing for a third term, triggering widespread rioting.
Doumbouya became interim president and promised a transition to democratic elections within three years.
ECOWAS rejected the timeline and imposed sanctions on junta members and their relatives, including freezing their bank accounts.
The military government later proposed to start the 24-month transition in January 2023, but opposition parties say it has done little to put in place institutions and a roadmap to return to constitutional rule.
CHAD
In April 2021, Chad's army took power after President Idriss Deby was killed on the battlefield while visiting troops fighting rebels in the north.
Under Chadian law, the speaker of parliament should have become president. But a military council stepped in and dissolved parliament in the name of ensuring stability.
Deby's son, General Mahamat Idriss Deby, was named interim president and tasked with overseeing an 18-month transition to elections.
The unconstitutional transfer of power led to riots in the capital N'Djamena that were put down by the military.
MALI
In August 2020, a group of Malian colonels led by Assimi Goita ousted President Ibrahim Boubacar Keita. The coup followed anti-government protests over deteriorating security, contested legislative elections and allegations of corruption.
Under pressure from Mali's neighbours, the junta agreed to cede power to a civilian-led interim government tasked with overseeing an 18-month transition to democratic elections to be held in February 2022.
But the coup leaders clashed with the interim president, retired colonel Bah Ndaw, and engineered a second coup in May 2021. Goita, who had served as interim vice president, was elevated to the presidency.
ECOWAS lifted some of the sanctions on Mali after the military rulers proposed a two-year transition to democracy and published a new electoral law. The country is scheduled to hold a presidential election in February 2024 to return to constitutional rule.
