It was not immediately clear if the troops outside national broadcaster RTB were from the mutineers or had been sent in by the government of the volatile West African state.

Soldiers at several army bases across the country rebelled on Sunday, demanding the sacking of the country's military top brass and more resources for the battle against Islamist insurgents.

Shots were also heard late Sunday near the private residence of President Roch Marc Kabore in the capital and witnesses reported seeing a helicopter above it.

The situation was tense and confused in the capital on Monday, where mobile internet had been cut since Sunday, making it difficult to verify rumours of a coup in progress.

Demonstrators protesting over the government's handling of the jihadist threat set fire to the headquarters of the ruling party at the weekend.

The government swiftly denied rumours of a putsch and a list of demands presented by the rebellious troops made no mention of trying to oust Kabore.
