Boko Haram leader, Abubakar Shekau, released a video message yesterday claiming a series of attacks in North-east Nigeria during the festive season.
According to AFP, the shadowy leader released his first video message in months amid a surge in violence casting doubt on the Nigerian Government's claim that the jihadist group is defeated.
"We are in good health and nothing has happened to us," Shekau said in the 31-minute video message spoken in the Hausa language common across northern Nigeria.
"Nigerian troops, police and those creating mischief against us can't do anything against us, and you will gain nothing."
"We carried out the attacks in Maiduguri, in Gamboru, in Damboa. We carried out all these attacks, he said."
The video then shows footage from a Christmas Day attack on a military checkpoint in Molai village on the outskirts of the Northeast Nigerian city of Maiduguri, which the military said was thwarted by troops after one hour of battle.
Boko Haram fighters in torn clothes were shown shooting from the back of battered pickup trucks.
Shekau's message comes during an acceleration of Boko Haram attacks and just days after the jihadists killed 25 people outside Maiduguri, the birthplace of the Islamist insurgency.
In December, Boko Haram attacked convoys of Nigerian soldiers and dispatched suicide bombers into crowded markets in towns across Northeast Nigeria.
At least 50 people were killed in November when a suicide bomber blew himself up at a mosque in Adamawa State.
But President Muhammadu Buhari said in his New Year address that Boko Haram has been "beaten."
"Isolated attacks still occur, but even the best-policed countries cannot prevent determined criminals from committing terrible acts of terror," Buhari said.
Shekau, a leader known for his lengthy, wild-eyed video messages, took over Boko Haram in 2009 after the death of its founder, Muhammad Yusuf.
Boko Haram, whose Islamist insurgency has left at least 20,000 people dead in Nigeria since it began in 2009, has long been fractionalised.
In 2016, it suffered a major split when the so-called Islamic State group recognised Yusuf's son, Abu Mus'ab al-Barnawi, as a leader.
