Story highlights

  • Nigeria is battling an Islamist insurgency that has claimed 3,000 lives since 2009
  • Boko Haram is fighting for stricter Sharia law in Nigeria's predominately Muslim north
  • Nigeria's military suspect Boko Haram was behind an attack on a college this week
  • At least 29 students were killed and several buildings torched in the Buni Yadi attack

Boko Haram is an Islamist militant group waging a campaign of violence in northeastern Nigeria, particularly in the states of Borno, Yobe and Adamawa.

The group's ambitions range from the stricter enforcement of Sharia law -- which is derived from the Koran as the "world of God" -- across the predominantly Muslim north of Nigeria, to the total destruction of the Nigerian state and its government.

The Nigerian government is struggling to control the bloodshed between the mainly Muslim north and Christian south that has claimed more than 3,000 lives since Boko Haram came to prominence in 2009, according to Human Rights Watch.

Human Rights Watch and Amnesty International have also accused Nigeria's military of committing atrocities against civilians.

After raising concerns with Nigeria's foreign minister last May, U.S. Secretary of State John Kerry said: "The government has acknowledged that there have been some problems ... they're working to try to control it."

Days after a deadly attack on a college in northeastern Nigeria, which the military suspects may have been committed by Boko Haram, we look back at the past year of attacks blamed on -- or claimed by -- the group.

February 26, 2014: At least 29 students die in an attack on a federal college in Buni Yadi, near the the capital of Yobe state, Nigeria's military says.

Authorities suspect Boko Haram carried out the assault in which several buildings were also torched.

February 15, 2014: Dozens of residents in northeastern Nigeria are killed in two separate attacks launched by Boko Haram, according to officials and residents.

They say scores of militants dressed in military uniforms storm the Christian farming village of Izghe, in Borno state, and open sporadic fire on residents, killing at least 106 people in an attack specifically targeting male residents.

In the second attack, suspected Boko Haram gunmen open fire on Doron Baga, a fishing village along Lake Chad. "They opened fire from all directions, forcing residents to jump into the lake in a bid to escape, and many drowned while others were gunned down," a survivor says.
