At least nine people have been killed and several more wounded in three suicide bombings in the city of Diffa in the south-east of Niger, close to the border with Nigeria.
Two of the suicide bombers were young women and the targets included an Islamic school.
Although no group has yet said it carried out the attacks, militant Islamist group Boko Haram has frequently targeted Diffa.
The area had, however, been relatively calm for several months until the bombings late on Monday evening.
