Nigeria forces foil suicide attack in north-east

 

The Nigerian authorities say they have killed three female teenage suicide bombers who attempted to attack a military checkpoint.
The incident happened on Wednesday night in the north-eastern city of Maiduguri.
Officials say the attackers' explosives were set off when they were shot at by troops.
One member of the security forces was injured.
No group has said it carried out the attempted attack, but Maiduguri was the birthplace of the Islamist militant group Boko Haram, and it has attacked the city many times.
