Neighbouring Mali faced conflict in Azawad that threatened to split the country. Since 2015, Burkina Faso has faced cross-border attacks and sporadic raids in its territory, the result of instability and unrest in neighboring countries. Two major attacks have occurred in the capital Ouagadougou in recent years: In 2016, attacks on a hotel and restaurant killed 30 people, including foreigners; and in 2017, similar attacks killed 19 people, including foreigners. Both of these attacks were carried out by Al-Qaeda in the Islamic Maghreb.Burkina Faso also faced an uprising in 2014 leading to the downfall of President Blaise Compaoré later that year.

With approximately 182 million inhabitants, Nigeria is the most populous country in Africa and the seventh most populous country in the world. Nigeria has one of the largest populations of youth in the world. The country is viewed as a multinational state, as it is inhabited by over 500 ethnic groups, of which the three largest are the Hausa, Igbo and Yoruba; these ethnic groups speak over 500 different languages, and are identified with wide variety of cultures. The official language is English. Nigeria is divided roughly in half between Christians, who live mostly in the southern part of the country, and Muslims in the northern part. A minority of the population practise religions indigenous to Nigeria, such as those native to Igbo and Yoruba peoples.

Document 11: Nigeria: The vast majority of Muslims in Nigeria are Sunni belonging to Maliki school of jurisprudence; however, a sizeable minority also belongs to Shafi madhhab. A large number of Sunni Muslims are members of Sufi brotherhoods. Most Sufis follow the Qadiriyya, Tijaniyyah and/or the Mouride movements. A significant Shia minority exists (see Shia in Nigeria). Some northern states have incorporated Sharia law into their previously secular legal systems, which has brought about some controversy. Kano State has sought to incorporate Sharia law into its constitution. The majority of Quranists follow the Kalo Kato or Quraniyyun movement. There are also Ahmadiyya and Mahdiyya minorities.
Document 12: Nigeria: Ethnocentrism, tribalism, religious persecution, and prebendalism have affected Nigerian politics both prior and subsequent to independence in 1960. Kin-selective altruism has made its way into Nigerian politics, resulting in tribalist efforts to concentrate Federal power to a particular region of their interests. Nationalism has also led to active secessionist movements such as MASSOB, Nationalist movements such as Oodua Peoples Congress, Movement for the Emancipation of the Niger Delta and a civil war. Nigeria's three largest ethnic groups (Hausa, Igbo and Yoruba) have maintained historical preeminence in Nigerian politics; competition amongst these three groups has fuelled corruption and graft.

The group gained prominence after it drove Iraqi government forces out of key cities in western Iraq in a 2014 offensive. The group is adept at social media, posting Internet videos of beheadings of soldiers, civilians, journalists and aid workers, and is known for its destruction of cultural heritage sites.
