At least 19 people were killed and 143 wounded on Thursday in a suspected twin suicide bomb attack in Cameroon's Kerawa City.
Located in the northern part of Cameroon, Kerawa is also near the Nigerian border, where there are frequent clashes between Boko Haram militants and government forces.
According to Anadolu Agency, the first blast hit a crowded market at around 11am local time (1000GMT), with the second one exploding 200 meters from a military camp a few minutes after.
Some local media reports have suggested that the number of deaths could be as high as 30.
A local government official said, he has been told the attackers were female suicide bombers, however, no group has claimed responsibility for the attacks. Similar incidents in the past have usually been claimed by the militant group Boko Haram.
Boko Haram has established a stronghold in northeastern Nigeria and has attacked its border neighbours Chad, Niger and Cameroon, after the three countries took part in an offensive against the militant group earlier this year.
In early 2015, African neighbours had managed to recapture some key territory back from Boko Haram, leading the militants to engage in more hit-and-run attacks.
Boko Haram was founded in 2002, as an opposition to Western-style education and began their military operations in 2009. They pledged loyalty to the self-proclaimed Islamic State of Iraq and Al Sham [ISIS] and announced itself as its West African Province in April 2015.
