464 killed in Nigeria, troops seek to end violence

More than 200 ethnic groups generally live peacefully side-by-side in the West African country, although 1 million people were killed in a civil war between 1967 and 1970 and there have been outbreaks of religious unrest since then.

Jos has been the centre of several major religious clashes in Africa’s most populous nation.

The November 2008 clashes killed around 700 people, according to U.S.-based Human Rights Watch, while more than 1,000 Jos residents died in similar fighting in September 2001.
