At least three people have been killed and 20 wounded in a suicide blast in northern Cameroon, officials have warned. A suicide bomber on a motorbike blew himself up on a bridge near the market in Mora, in the Far North Region.
Midjiyawa Bakari, governor of the Far North region, identified the victims as a teacher, a high school student and a person from a neighbouring town, and said five of the wounded were in "serious condition", according to news agency AFP.
No group has claimed responsibility, but suspicions are likely to fall on Nigeria-based Boko Haram terrorists, who also carry out attacks in northern Cameroon.
Nigeria is heading an ongoing regional offensive against the Islamist outfit, which recently split into two factions.
The task force consists of 8,700 troops from Nigeria, Niger, Chad, Cameroon and Benin. Mora is home to the headquarters of the multinational force.
The town was previously attacked in September 2015, when two female suicide bombers detonated themselves in the Galdi neighbourhood, killing five people.
In January, Cameroon temporarily closed most of its markets along the border with north-east Nigeria following deadly attacks blamed on Boko Haram.
Although some argued it would undermine people's businesses, authorities said the decision was made for security reasons, as attackers often disguise themselves as traders and detonate explosives in crowded places such as markets.
Who are Nigeria's Boko Haram terrorists?
Boko Haram, which has renamed itself Iswap, fights against Western influence in Nigeria and aims to impose its version of Sharia law throughout territories it occupies.
The group launches attacks in Nigeria and neighbouring countries in a bid to take control of more territory. Three Nigerian states − Adamawa, Borno and Yobe − have been under a state of emergency since May 2013.
Boko Haram has killed more than 20,000 people since 2009 and was deemed the world's deadliest terror group, surpassing Islamic State, in November 2015.
Nigeria has also become the world's third-most terrorised country as a result of the group's violent insurgency.
