The incidence in a cattle market in Maiduguri scattered animals and their sellers into pieces.

A bomb explosion at a market in the northeastern Nigerian city of Maiduguri killed at least 50 people on Tuesday June 2, 2015, according to a witness who helped evacuate victims from the scene, Africatimes reports. “We have been helping to evacuate the corpses and I can say over 50 people died from the attack,” Isa Mohammed, a vigilante militia member, told reporters. “It is the biggest abattoir in Maiduguri and many people were engaged in the buying and selling of animals when the time bomb exploded,” he added.

Although no group has claimed responsibility for the attack, suspicion is likely to fall on Boko Haram terrorists, who recently resumed attacks in Maiduguri and other towns in north-eastern Nigeria. Borno, Yobe and Adamawa are the Nigerian States that mostly bear the brunt of Boko Haram’s insurgence, which has claimed thousands of lives since 2009.

Tuesday’s attack occurred days after newly elected President Muhammadu Buhari announced it would relocate military headquarters from Abuja to Maiduguri. The extremist group which seeks to impose Islamic law across northern Nigeria has repeatedly attacked Maiduguri, the largest city in the northeast, since the newly elected president has designated it as the new headquarters in the war to curb the terrorist uprising.

Over the weekend, more than 30 people died in another Boko Haram assault involving another suicide bombing and rocket-propelled grenades. Also on Tuesday June 2, 2015, Boko Haram released a new video that allegedly shows militants shooting wounded Nigerian soldiers in the head and beheading a man in civilian clothes as well as charred parts claimed to be the remnants of a downed Nigerian jet fighter.

Meanwhile, in a video released on Tuesday June 2, 2015, Boko Haram rejected reports that a military offensive had routed the terrorist group from Nigeria’s Borno State, where it maintains a last stronghold in the Sambisa forest reserve. An identified speaker in the video called Nigeria, Cameroon, Chad and Niger – which launched a coordinated, cross-border offensive against the terrorist group in February – the “lying coalition partners.” The video did not however feature the group’s leader, Abubakar Shekau, who has figured prominently in other Boko Haram videos. Since the four-nation offensive was launched earlier this year, the Nigerian military has succeeded in flushing the rebels out of several towns in Nigeria’s northeast Borno State, the Islamist group’s stronghold. The militants are showing a return to guerrilla tactics since losing the territory they gained last year.
