A day after hitting Maiduguri, the Borno state capital where 11 people were confirmed dead, Boko Haram has attacked northeastern Cameroon.

14 people were killed while 30 were injured security sources said Thursday.

The bombings, which took place on Wednesday evening in Waza near the Nigerian border, targeted a busy area in the market town, the sources said.

The bombers struck an area with "restaurants, telephone cabins and kiosks", a local official said.

"The town has been sealed off. Nobody can enter and nobody can leave," the source said, adding that some of the wounded were in "quite serious" condition.

Though the Boko Haram movement started in Nigeria, the Islamic State-affiliated group has carried out frequent attacks in Cameroon, Chad and Niger, prompting the formation of a regional force to fight back.

Cameroon's Far North region, which borders Nigeria, has seen a resurgence in attacks blamed on Boko Haram after months of relative calm.
