Baku-APA. Police authorities in northeast Nigeria's Borno State on Friday confirmed seven people were killed when a bomb went off at Gwoza, a community that shares border with Cameroon at the edge of the Sahara Desert, APA reports quoting Xinhua.
Three people were also injured in the incident, according to state police chief, Lawan Tanko, who spoke with reporters in Maiduguri, the capital of the northern state.
He said investigation by police revealed that a bus conveying the victims ran over an improvised explosive device (IED) suspected to be planted by Boko Haram, a sect which proves to be a major security threat in the West African country.
Injured victims were rushed to a nearby hospital, he added, saying the explosion occurred at Kuthra Village of Gwoza local government, which is about 135 km from Maiduguri.
In an earlier Xinhua report, Idrissa Timta, a traditional ruler of the local community, described the situation at the area as " tense" when he visited Governor Kashim Shettima on Friday.
Briefing the governor on the incident, Timta said security operatives, who quickly cordoned off the area, delayed him for more than an hour, so as to clear the road and get security report, before allowing him to embark on his journey.
No group has claimed responsibility for the attack in the northeast state but it is presumed to be a perpetration of Boko Haram.
Early this week, at least 85 people were confirmed killed in a Boko Haram attack in Konduga local government area of Borno State.
Adamawa, Borno and Yobe -- three neighboring states in the restive northeastern region of Nigeria -- are under a state of emergency declared by President Goodluck Jonathan eight months ago.
Last week, Alex Badeh, Nigeria's newly appointed defense chief, vowed to end the insurgency of Boko Haram by April.
More than 1,500 people, including women and children, had been killed in the five-year insurgency of the sect.
