A suicide bomber on Sunday at a market in north Cameroon, killed at least three people and wounded about 24 persons.

The suspected bomber on motorbike attacked the open market where Islamist Boko Haram is waging an insurgency for a breakaway Islamic state across four countries, authorities said.

The bomber was killed in the attack in Mora, Far North province, a senior military official said.

He said that it was possible one of the three victims was on the bike. Another security source said authorities were convinced this was the work of Boko Haram.

Nigeria, Chad, Cameroon and Niger are the four countries most affected by the militant group.

In January, Cameroon temporarily closed most of its markets along the border with north-east Nigeria following deadly attacks blamed on Boko Haram.

“Sunday is a big market day,” Communications Minister Issa Tchiroma said by telephone, confirming the details and death toll in the Mora attack. “There were also six people seriously wounded who were transported out by helicopter to Maroua.”

He said that “the situation is currently under control”.

Cameroon has been frequently hit by suicide attacks. A suicide bomber killed at least 11 people when he blew himself up close to a mosque in Cameroon near the Nigerian border in late June.
