Boko Haram killed thousands of people, abducted at least 2000 women and girls and forced more than a million to flee their homes. Through a campaign of almost daily killings, bombings, abductions, looting and burning, Boko Haram crippled normal life in north-east Nigeria. Schools, churches, mosques and other public buildings were destroyed. Boko Haram brutally mistreated civilians trapped in areas under its control.
