Mali president offers concessions to end political stalemate
Mali has been struggling to contain an Islamist insurgency that first emerged in the north in 2012, before spreading to the centre of the country and to neighbouring Burkina Faso and Niger.
Thousands of soldiers and civilians have been killed in the conflict to date, and hundreds of thousands of people have been forced from their homes.
On Wednesday evening, Keita proposed in a televised speech the appointment of new judges to the country's constitutional court, which has been at the centre of controversy since April.
Following a long-delayed parliamentary poll in March - which Keita's party won - the court overturned the provisional results for about 30 seats on 29 April, in a decision that triggered protests in several Malian cities.
The move saw several members from Keita's party elected to the parliament, and is viewed by many as having ignited Mali's latest political crisis.
But Keita, who has been in power since 2013, suggested in his speech on Wednesday that new constitutional court judges could revisit that decision.
The embattled president's attempt to appease Mali's growing opposition movement appears to have fallen on deaf ears.
One protest leader, Moussa Sinko Coulibay, tweeted on Thursday the speech had "completely failed".
"We massively invite women [to demonstrate]. President IBK has not met our expectations," the leader of the women's wing of the protests, Fatoumara Oulare, said Thursday.
Malian singer Salif Keita also tweeted a call to protest on Friday.
The president is on increasingly shaky political ground as protests continue, alarming the international community which is keen to avoid Mali sliding into chaos.
The 75-year-old has mooted several reforms since demonstrations began in a bid to appease protesters, such as the formation of a new national unity government.
Last week, opposition leaders said they wanted to engage in dialogue with the president, dropping demands for his resignation in favour of the dissolution of parliament and the establishment of a transition government.
Since then, back-and-forth talks between the opposition and Keita have failed to achieve a breakthrough, however, with the president refusing to dissolve parliament.
