Nigeria's ailing President Umaru Yar'Adua, who gave amnesty to armed militants in the troubled oil-rich Niger Delta region, has died, the country's information minister said Wednesday. He was 58.
Yar'Adua had not been seen in public since November, when he went to Saudi Arabia for treatment of an inflammation of tissue around his heart. He was diagnosed with that condition, acute pericarditis, last fall after he complained of chest pain.
He returned to Nigeria in February, but had remained out of sight.
Vice President Goodluck Jonathan has served as the country's acting leader since Yar'Adua fell ill.
