40 people killed in Niger in attack near Mali border
In the Mali border region, there have been recurring attacks.
On March 16, at least 58 people were killed in an attack on market traders in the region of Tillaberi, the government said.
Niger has also seen demonstrations after the recent presidential election.
At the end of February, the electoral commission declared former foreign minister Mohamed Bazoum, a close ally of outgoing President Mahamadou Issoufou, the winner with almost 56 per cent of the vote.
Former president and opposition candidate Mahamane Ousmane slammed the result as fraudulent and claims he is the winner.
The Constitutional Court on Sunday confirmed Bazoum’s victory.
