Christian-Muslim Harmony in Nigeria in Jeopardy Amid Attacks by Islamic

In the past three years, thousands of Christians have died at the hands of Boko Haram, an extremist group based in northern Nigeria, says Cardinal John Onaiyekan.
A report by Human Rights Watch, published in January, indicates that more than 3,000 people have been killed since 2009 by Boko Haram, a northern-based extremist group once known as the Nigerian Taliban.
During his lecture on Muslim-Christian relations at the University of St. Michael's College (Toronto), Cardinal John Onaiyekan, Roman Catholic Cardinal Archbishop of Abuja, warned that the violence perpetrated by the extremist group is threatening the Muslim-Christian harmony in Nigeria.
Since 2009, the extremist group has launched numerous gun or bomb attacks against churches, schools, police stations, military facilities, newspaper offices and even against the United Nations building in Abuja, the Nigerian capital.
Boko Haram militants also raid Christian homes to demand conversion to Islam or death.
Mainstream Muslim leaders have denounced Boko Haram's methods as against the principles of Islam. In response, the group has assassinated a number of Muslim clerics.
