At least 50 people have been killed and dozens were wounded on Tuesday after a bomb exploded in a crowded market in Nigeria's northeastern city of Maiduguri, Reuters has reported.
No groups claimed responsibility for the Tuesday’s explosion in the cattle market but Boko Haram is known to have launched similar attacks in Maiduguri and the rest of Borno State.
A military source said that the bomb, which was concealed under a butcher's table in the market, went off at around 1 p.m. local time, killing shoppers and passersby.
A 12-hour curfew was imposed in the city overnight following the attack.
Other attacks in the area have been blamed on Boko Haram, including one on a mosque that killed more than 30 people in Maiduguri on Saturday at a mosque near the popular ‘Monday Market’, a few hours after the new president, Muhammadu Buhari, took his oath of office, vowing to destroy Boko Haram.
Nigeria's military on Saturday also repelled another Boko Haram attack on Maiduguri, hours after President Muhammadu Buhari took office.
The incident followed a rocket attack on Friday night fired by Boko Haram that hit a residential building in the city, killing at least seven people and injuring a dozen others, witnesses and security officials said according to local news sources.
The violence poses a great challenge to the country's President Buhari, who announced on Friday that he is moving the military's headquarters from the capital Abuja to Maiduguri to better tackle Boko Haram.
Condemning the terrorist attack, Buhari said that the government would not tolerate any criminal elements or anarchy.
The new president is travelling to Chad and Niger on Wednesday on his first official trip outside Nigeria, spokesman Garba Shehu said.
13,000 people have been killed by Boko Haram raids since 2009 and 1.5 million were forced to migrate from their homes.
