Twin bombings in the northern Nigerian city of Kaduna killed at least 82 people on Wednesday and Boko Haram is suspected to be responsible. One of the attacks in a crowded marketplace targeted former president and opposition leader Muhammadu Buhari. A Red Cross official said 50 were killed at that bombing. An additional 32 were killed earlier in the day in a bombing that took place as a popular moderate Muslim cleric, Sheikh Dahiru Bauchi, was about to lead his congregation in prayer. (Neither Buhari nor Bauchi were killed.) Boko Haram has launched a series of bombings in the northeastern part of the country over the past three months.
