Nigeria's President Fires Security, Defense Chiefs

6/28/2012, 3:32 p.m.

Amid mounting violence in the north, Nigeria's President Goodluck Jonathan has fired his national security adviser and defense minister.

While it has remained unclear who will replace Defense Minister Bello Mohammed, the president's security aide Owoye Azazi will be replaced by Sambo Dasuki, a retired colonel from the Muslim North.

The announcements were made recently following a spate of attacks that targeted at least three churches, and in which about 150 people were killed.

Reports also state that new incidences of rioting occurred later, and that curfews have since been imposed in both northeastern cities of Kaduna and Damaturu.

Meanwhile, President Jonathan has faced mounting criticism over the manner in which growing insurgency has been responded to, with analysts noting serious concern that residents could increasingly take the law into their own hands if the authorities do not tackle the problem.
