Al-Qaida and IS-linked violence in Africa’s Sahel belt set to hit record levels this year

Twenty-five years after 9/11, figures compiled by conflict monitor underline how Sahel region has become centre of Islamist terror

Islamist extremist violence in Africa's Sahel region is set to reach historic highs after a series of sweeping offensives by groups linked to al-Qaida and Islamic State, according to new figures compiled by the conflict monitor Acled.

As the US marks the 25th anniversary of the 9/11 attacks launched by al-Qaida against targets in Washington and New York, the statistics underline the continued expansion of the veteran organisation in parts of Africa - in stark contrast with its relative weakness elsewhere.
