“I strongly condemn the arrest of President Ibrahim Boubacar Keita, the Prime Minister and other members of the Malian Government and call for their immediate release,” Mahamat wrote.
He added that he called on “the mutineers to cease all use of violence,” and asked the international community to oppose any use of force.
Earlier on Tuesday, Malian Prime Minister Cisse had posted a plea to troops on Facebook, asking the military to put down its arms and engage in dialogue.
“The government calls for reason and a patriotic sense and asks for the use of arms to be stopped. There are no problems that cannot be solved in dialogue,” Mali’s prime minister wrote, in a statement that appears to have been posted before his reported detention.
Unrest across Bamako
On Tuesday, crowds took to the streets in Bamako, surrounding the capital city’s independence monument. In footage of the city, protesters on motorbikes could be seen cheering at news of the suspected coup, while some opposition supporters celebrated with Malian flags and vuvuzelas.
A building owned by Mali’s Minister of Justice was also looted and set on fire.
The unrest in Mali’s capital followed reports of an attempted mutiny Tuesday morning at a military camp 15 km outside of the city, confirmed to CNN by a diplomatic source who had been briefed by local officials. The source spoke on the condition of anonymity, as they were not authorized to speak on the subject.
The source said the attempted mutiny took place in Kati, at the same camp that a successful military coup was launched back in 2012.
Months of discontent
Mali’s 75-year-old President Keita has faced growing public discontent since May, after the country’s top constitutional court overturned results from disputed parliamentary elections, paving the way for Keita’s party to occupy a majority of the vacant seats.
Disputes over the polls have also sparked post-electoral violence in several districts in the capital and other towns in March.
Mali previously faced a major rebellion in 2012, after a coup staged by mid-ranking army officers opened an opportunity for Jihadi groups and rebels from the country’s long marginalized Tuareg to take over a significant part of the country.
Mali shares borders with Algeria, Niger and Mauritania, and all four countries have struggled with the growing presence of Islamist groups in the region.
The European Union on Tuesday condemned the apparent “coup attempt” underway in Mali.
“The European Union condemns the coup attempt underway in Mali and rejects any unconstitutional change,” EU High Representative for Foreign Affairs Josep Borrell said in a statement.
“This can in no way be an answer to the deep socio-political crisis that has hit Mali for several months,” he said.
The French and US embassies in Mali on Tuesday warned citizens to stay home amid the violence.
“The US Embassy is aware of gunfire and unrest in the area of Kati, as well as ongoing police/military operations in Bamako,” the US embassy said in a statement.
“There have been multiple reports of gunfire throughout the city as well as reports of soldiers driving in trucks and firing their weapons in the air. There are continued reports of demonstrators gathered at the Monument de l’Independance. The US recommends all US citizens avoid these areas, if possible.”
And US Africa Command said it was aware of the suspected coup. The US has a limited number of personnel in Mali, who primarily perform counter terrorism activities with local and international partners.
“We are aware of the events in Mali. All US service members are accounted for. We will continue to monitor this situation,” US Africa Command said in a statement Tuesday.
