Roch Kaboré, the President of Burkina Faso, has reportedly been detained, a report said.
The BBC reports that mutinying soldiers seized the president, after they demanded that he sack military chiefs and allocate more resources to the fight against Islamist militants.
Gunfire was allegedly heard overnight near the presidential palace and at barracks in the capital, Ouagadougou.
The government on Sunday denied suggestions of a military coup or that the president was under arrest.
Video from the capital appears to show armoured vehicles – reportedly used by the presidency – peppered with bullet holes and abandoned in the street
A night-time curfew has since been imposed on the capital.
Meanwhile, the president’s location is unknown, but AFP news agency quoted security sources as saying that he and other government ministers are at the Sangoule Lamizana barracks in the capital.
