ABUJA, Nigeria (AP) — Nigeria’s health minister says three wounded victims have died, raising the toll to 75 dead in the massive blast at a busy bus station in Nigeria’s capital.

Minister Onyebuchi Chukwu visited some of the wounded in hospitals Tuesday, and put their number at 141. He said the previous figure of 164 wounded had counted some patients twice.

Chukwu said the death toll will likely increase as pathologists determine how many victims were blown apart.

President Goodluck Jonathan has blamed Islamic extremists for Monday’s blast during morning rush hour.

The explosion just miles from Nigeria’s seat of government is increasing doubts about the military’s ability to contain an Islamic uprising that has killed more than 1,500 people this year. The extremist group’s leader had threatened to attack Abuja and neighboring Cameroon.
