Burkina Faso: Senegalese president to mediate today
This follows the death of three people and yesterday's military coup in Ougadougou.
At least three people have died in street protests following the overthrow of interim President Michel Kafando, less than a month ahead of scheduled elections.
Burkinabe went to bed on Wednesday and woke the following morning to find the presidential guard had seized power.
A military official announced on the country's state-run television station that the government has been dissolved.
Kafando's being held captive along with his prime minister and housing minister.
Head of the military junta is General Gilbert Diendere, who was chief of staff for Blaise Campaore, the country's president for 27 years who was ousted a year ago when he sought to prolong that rule.
As regional mediator, Sall's first job will be securing the release of Kafando and others held captive by the putschists.
