Mutinying soldiers in the West African nation of Guinea detained President Alpha Conde after hours of heavy gunfire rang out near the presidential palace in Conakry.

Hundreds of people celebrated on the streets with members of Guinea’s armed forces after Conde’s arrest. The coup-makers announced on state television on Sunday the government had been dissolved.

They also announced plans to replace Guinea’s governors with regional military commanders.

The country’s borders were closed and its constitution declared invalid in the announcement read by army Colonel Mamady Doumbouya. “The duty of a soldier is to save the country,” he said.

A video emerged showing the 83-year-old Conde, looking tired and dishevelled, in military custody.

Conde, in power for more than a decade, had seen his popularity plummet since he sought a third term last year, saying term limits did not apply to him.
