A bomb attack killed around 50 people in a packed market in northeastern Nigeria on Tuesday, according to sources.
The blast took place at around 1:30pm local time in Sanon Gari, a town in Borno state, an area known to be the heartland of Boko Haram.
"So far, 52 people are injured, 47 dead persons have been removed from the market," a member of a civilian group, Umar Kidda, told Reuters.
A military source announced around 50 people had been killed after the attack.
While no one has yet claimed responsibility for Tuesday's bombing, suspicions are on Boko Haram because of the similar attacks of the militant group in the region.
The militant group has resorted to carrying out a number of suicide attacks in the region, killing dozens of people, including soldiers from Chad, Nigeria, Cameroon, and Niger.
Recently, Nigeria, Cameroon, Chad and Niger have been cooperating against Boko Haram which has been fighting a six-year insurgency in a bid to establish a state of its own in northern Nigeria and other neighbouring territories, including areas surrounding Lake Chad.
More than 13,000 people have been killed by Boko Haram’s six-year insurgency and over 1 million people are displaced internally in Nigeria.
Boko Haram had previously announced its pledge of allegiance to ISIS and calls itself West Africa Province of the militant group.
