The Prime Minister of Burkina Faso, Paul Kaba Thieba, has resigned from office along with his entire cabinet.

No reason was given for the move, which was announced in a televised statement by the country's president.

Mr. Thieba, a former economist, had held the position since January 2016 when he was nominated by President Roch Marc Christian Kabore.

His government has faced growing pressure over a rise in the number of kidnappings and jihadist attacks.

Recent high-profile disappearances of foreign nationals have led to direct calls for Mr. Thieba's resignation, as well as that of his defence and security ministers.

In his statement, President Kabore expressed his gratitude for their service. He said he hoped to form a new government soon.
