Suspected Islamist militants from Nigeria's Boko Haram group have killed at least four people in suicide attacks across the border in Niger.
The dead included three civilians and a soldier and four attackers also died during the attacks in Niger's southeastern region of Diffa.
Niger, Cameroon and Chad have all suffered a spillover of violence from Boko Haram's northern Nigerian strongholds.
Niger has arrested at least 1,100 suspected Boko Haram militants this year and has placed its Diffa region under a state of emergency.
Diffa, which borders Nigeria, has suffered at least 57 attacks since February.
At least 150,000 refugees seeking protection from Boko Haram attacks in Nigeria live in Niger's Diffa region.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
