He said several dozen others were wounded, including 15 who were taken to the hospital in Mora.
Bakari blamed the bombings on Boko Haram, the Nigerian armed group that has carried out attacks and kidnappings in Cameroon as it has widened its armed campaign to the area around Lake Chad.
Northern Cameroon has suffered from the overflow of violence linked to Boko Haram in recent years, which launches frequent cross-border raids.
Nigerian refugees have flooded across the border and local residents have been forced to flee their homes.
Villages and towns in the area have regularly been targeted by suicide bombers.
A similar attack in Kolofata killed nine people in September 2015.
Thousands of troops have been deployed to the area in a bid to stem the violence.
