Nigerian soldiers angered by the death of an officer have shot and killed more than 30 civilians. The militant Islamic group Boko Haram is active in the area, but a journalist at the scene said there were no signs the dead were militants. Soldiers also set fire to dozens of homes and businesses. One Nigerian soldier said the attack came in response to a bombing earlier in the day that killed a lieutenant. Meanwhile, Nigerian President Goodluck Jonathan is pledging aid to tens of thousands of Nigerians displaced by the country’s worst flooding in 50 years. The Red Cross said last week the floods have killed at least 148 people.
