Police spark unrest in Burkina Faso

Witnesses say police in and around Burkina Faso's capital shot into the air in the latest episode of unrest in the impoverished West African nation.

A senior police officer says Thursday's unrest is a bid for the implementation of a new salary scheme and the dismissal of the police chief. He asked for anonymity as he is not authorized to speak to journalists.

On Wednesday, angry merchants torched several buildings in the city of Koudougou, echoing student protests there last week. Student protests first started in February.

Soldiers also started demonstrations around the country two weeks ago. That unrest prompted President Blaise Compaore to dissolve and re-create his government, with himself as defense minister.
