Protesters in Burkina Faso siding with soldiers who staged mutinies at several barracks in the country, set fire to the headquarters of the ruling party in the capital.
The unrest comes as soldiers staged an attempted coup, demanding the sacking of the country's military top brass, and the allocation of more resources for the seven-year clash against Islamist insurgents.
The soldiers demand that the top generals be replaced, while also calling for better care for injured troops and better support for the families of soldiers killed in battle.
The government has denied reports of a military takeover, but are on high alert, as governments in West and Central Africa have seen successful coups over the past 18 months in Mali and Guinea.
