At least two people are reported to have died during protests in Senegal, the first casualties of unrest that erupted after presidential elections scheduled for this month were postponed until the end of the year.
Geography student Alpha Yero Tounkara died amid protests at a university in the northern city of Saint-Louis, the interior ministry confirmed.
The ministry said in a statement that his death would be investigated, but denied that its forces were involved.
The second victim has been named by the media as Modou Gueye, a street vendor in the capital Dakar.
While authorities have not publicly confirmed his death, RFI spoke to a relative who said Gueye was shot in the southwest neighborhood of Dakar.
The Red Cross said it was compiling a death toll across Senegal from violent protests, the first day of widespread unrest since President Macky Sall canceled elections scheduled for February 25.
In Dakar, police fired tear gas to stop demonstrators gathering in a central square. Hundreds of demonstrators threw stones at the police and set tires on fire.
Clashes spread to other areas of the capital, shutting down major roads, train lines and markets.
Demonstrations also took place in other cities, while the civil society movement Aar Sunu Election ("Defend Our Elections") called on teachers to go on strike.
The group has called for more protests today.
