VATICAN CITY (AFP) - Pope Benedict XVI on Sunday appealed for "an end to all violence" in Nigeria after deadly attacks by Islamists claimed at least 150 lives in the north of the country. The attacks Friday targeted Christian churches as well as police stations and an army base in Damaturu and Maiduguri and two small towns. "I follow with apprehension the tragic events reported in recent days in Nigeria," the pope said after his weekly Angelus prayer. "While I pray for the victims, I ask for an end to all violence, which does not resolve problems but increases them, sowing hatred and divisions," the pontiff added.
