Security issues
Jonathan's administration was heavily criticized for its failure to tackle insecurity. The first major challenge was the October 2010 Independence Day bombing. Okah told the court that President Jonathan and his aides organised the attacks in Abuja in a desperate political strategy to demonise political opponents, including former military head of state General Ibrahim Babangida, and to win popular sympathy ahead of the elections.
On 29 May 2011, a few hours after Goodluck Jonathan was sworn in as president, several bombings purportedly by Boko Haram killed 15 and injured 55. On 16 June 2011, Boko Haram claimed to have conducted the Abuja police headquarters bombing, the first known suicide attack in Nigeria. Two months later the United Nations building in Abuja was bombed, signifying the first time that Boko Haram attacked an international organisation. In December 2011, it carried out attacks in Damaturu killing over a hundred people, subsequently clashing with security forces in December, resulting in at least 68 deaths. Two days later on Christmas Day, Boko Haram attacked several Christian churches with bomb blasts and shootings.
According to Reuters, Shekau took control of the group after the death of Yusuf in 2009. Authorities had previously believed that Shekau died during the violence in 2009. By early 2012, the group was responsible for over 900 deaths. On 8 March 2012, a small Special Boat Service team and the Nigerian Army attempted to rescue two hostages, Chris McManus and Franco Lamolinara, being held in Nigeria by members of the Boko Haram terrorist organisation loyal to al-Qaeda. The two hostages were killed before or during the rescue attempt. All the hostage takers were reportedly killed.
On 18 March, a bus station was bombed in Kano, with several casualties. In May 2013, Nigerian government forces launched an offensive in the Borno region in an attempt to dislodge Boko Haram fighters after a state of emergency was called on 14 May 2013. The state of emergency, applied to the states of Borno, Yobe, and Adamawa in northeastern Nigeria. The offensive had initial success, but the Boko Haram rebels were able to regain their strength. Although initially offering amnesty, by June 2013 he ordered a 20-year jail term for anyone found to be in support of Boko Haram. In July 2013, Boko Haram massacred 42 students in Yobe, bringing the school year to an early end in the state. On 5 August 2013, Boko Haram launched dual attacks on Bama and Malam Fatori, leaving 35 dead.
On 16 January 2014, it was reported that Jonathan had sacked his military high command in response to their inability to end the Islamist-led insurgency in Northern Nigeria. On 14 April, over 200 schoolgirls in Chibok were kidnapped. A few weeks later in May, a terrorist offensive was launched against the military in Chibok. Many demonstrations called for the government to be more responsive; Jonathan asked that demonstrators focus on blaming Boko Haram itself for the abductions. Jonathan initially denied that there had been any abduction at all, but then later signaled his government would do a prisoner release in exchange for the kidnapped girls. Discussions then took place in Paris with foreign ministers from France, Britain, the United States and Israel, where he agreed no deals should be struck with terrorists. He then called off the exchange at the last minute on 24 May 2014. This reportedly enraged Boko Haram leaders.
In May 2014, two bombs exploded in Jos, resulting in the deaths of at least 118 people and the injury or over 56 others. During the June 2014 Northern Nigeria attacks, a plaza in the capital city was bombed and hundreds of villagers attacked in a two-day killing spree in Kaduna. In November, Boko Haram bombed the city of Kano, attempting to assassinate the Emir Muhammadu Sanusi II. Starting in late 2014, Boko Haram militants attacked several Nigerian towns in the North and captured them. This prompted the Nigerian government to launch an offensive, and with the help of Chad, Niger, and Cameroon, they have recaptured many areas that were formerly under the control of Boko Haram. In late 2014, Boko Haram seized control of Bama, according to the town's residents. In December 2014, it was reported that "people too elderly to flee Gwoza Local Government Area were being rounded up and taken to two schools where the militants opened fire on them." Over 50 elderly people in Bama were killed. A "gory" video was released of insurgents shooting over a hundred civilians in a school dormitory in the town of Bama.
Between 3 and 7 January 2015, Boko Haram attacked the town of Baga and killed up to 2,000 people, perhaps the largest massacre by Boko Haram. On 10 January 2015, a bomb attack took place at the Monday Market in Maiduguri, killing 19 people. The city is considered to be at the heart of the Boko Haram insurgency. In the early hours of 25 January 2015, Boko Haram launched a major assault on the city. On 26 January 2015 CNN reported that the attack on Maiduguri by "hundreds of gunmen" had been repelled, but the nearby town of Monguno was captured by Boko Haram. The Nigerian Army claimed to have successfully repelled another attack on Maiduguri on 31 January 2015. Starting in late January 2015, a coalition of military forces from Nigeria, Chad, Cameroon, and Niger began a counter-insurgency campaign against Boko Haram. On 4 February 2015, the Chad Army killed over 200 Boko Haram militants. Soon afterwards, Boko Haram launched an attack on the Cameroonian town of Fotokol, killing 81 civilians, 13 Chadian soldiers and 6 Cameroonian soldiers.
On 17 February 2015 the Nigerian military retook Monguno in a coordinated air and ground assault. On 7 March 2015, Boko Haram's leader Abubakar Shekau pledged allegiance to the Islamic State of Iraq and the Levant (ISIL) via an audio message posted on the organisation's Twitter account. Nigerian army spokesperson Sami Usman Kukasheka said the pledge was a sign of weakness and that Shekau was like a "drowning man". That same day, five suicide bomb blasts left 54 dead and 143 wounded. On 12 March 2015, ISIL's spokesman Abu Mohammad al-Adnani released an audiotape in which he welcomed the pledge of allegiance, and described it as an expansion of the group's caliphate to West Africa. Following its declaration of loyalty to ISIL, Boko Haram was designated as the group's "West Africa Province" (Islamic State West Africa Province, or ISWAP) while Shekau was appointed as its first vali (governor). Furthermore, ISIL started to support Boko Haram, but also began to interfere in its internal matters. For example, ISIL's central leadership attempted to reduce Boko Haram's brutality toward civilians and internal critics, as Shekau's ideology was "too extreme even for the Islamic State".
On 24 March 2015, residents of Damasak, Nigeria said that Boko Haram had taken more than 400 women and children from the town as they fled from coalition forces. On 27 March 2015, the Nigerian army captured Gwoza, which was believed to be the location of Boko Haram headquarters. On election day, 28 March 2015, Boko Haram extremists killed 41 people, including a legislator, to discourage hundreds from voting. Niger Army soldiers during counter-insurgency operations against Boko Haram in March 2015. In March 2015, Boko Haram lost control of the Northern Nigerian towns of Bama and Gwoza (believed to be their headquarters) to the Nigerian Army. The Nigerian authorities said that they had taken back 11 of the 14 districts previously controlled by Boko Haram. In April 2016, four Boko Haram camps in the Sambisa Forest were overrun by the Nigerian military who freed nearly 300 females. Boko Haram forces were believed to have retreated to the Mandara Mountains, along the Cameroon–Nigeria border. On 16 March 2015, the Nigerian army said that it had recaptured Bama. On 27 March 2015, the day before the Nigerian presidential election, the Nigerian Army announced that it had recaptured the town of Gwoza from Boko Haram.
By April 2015, the Nigerian military was reported to have retaken most of the areas previously controlled by Boko Haram in Northeastern Nigeria, except for the Sambisa Forest. In May 2015, the Nigerian military announced that they had released about 700 women from camps in Sambisa Forest.
