A female TikToker accused of helping Mali's army has been seized and killed execution-style by suspected jihadists.

Mariam Cissé, said to be in her 20s and with over 100,000 TikTok followers, posted videos about life in her Tonka hometown in the northern Timbuktu region and often expressed support for the army.

Her death has shocked the nation, which has been grappling with a jihadist insurgency since 2012. State TV said she had simply wanted to promote her community and support the army through her TikTok posts.

Mali is grappling with a fuel blockade imposed on the capital by jihadist groups that has severely disrupted daily life, with the African Union expressing "deep concern".

Ms Cissé was seized by the suspected jihadists while live-streaming from a market in a neighbouring town, French public radio RFI reported.
