Nigerian president dies after long illness

LAGOS, Nigeria (AP) - Nigerian President Umaru Yar'Adua, whose election marked the first peaceful transition of power from one civilian to another in a nation once plagued by military coups, has died, his spokesman said. He was 58.

Yar'Adua's death Wednesday comes following a lengthy illness and almost three months after his vice president assumed control of Africa's most populous nation.

Spokesman Olusegun Adeniyi said Yar'Adua died at the Aso Rock presidential villa with his wife Turai at his side. Adeniyi and other officials did not give a cause of death.

Yar'Adua had a long history of kidney ailments and recently suffered from an inflamed heart.

Yar'Adua will be buried before sundown today afternoon in his home state of Katsina in accordance with his Muslim faith, said Ima Niboro, a spokesman for Goodluck Jonathan, the country's acting president.

"Nigeria has lost the jewel on its crown and even the heavens mourn with our nation tonight," Jonathan said in a statement. Jonathan declared today a holiday as part of seven days of mourning for Yar'Adua.

Top government ministers flooded into the presidential villa late Wednesday night to meet with Jonathan, who offered condolences to Yar'Adua's wife before beginning work as the country's head of state, Niboro said.

Under Nigeria's constitution, Jonathan now becomes president until the next elections scheduled to be held by April 2011 - less than a year away. He also will nominate a vice president, subject to Senate approval.

U.S. President Barack Obama called Yar'Adua a man of "profound personal decency and integrity."

"President Yar'Adua worked to promote peace and stability in Africa through his support of Nigerian peacekeeping efforts as well as his strong criticism of undemocratic actions in the region," Obama said in a statement.

Born into one of Nigeria's best-known political families in 1951, Yar'Adua got his start as the governor of Katsina state. The soft-spoken former chemistry professor later emerged as the consensus pick among the ruling Peoples' Democratic Party, run by then-President Olusegun Obasanjo, a former military dictator.

Yar'Adua's election as president in 2007 was meant to end a cycle of military takeovers and cement democratic rule. However, international observers said the vote was rigged, even though Yar'Adua wasn't widely considered responsible.

"We acknowledge that our elections were not perfect and had lapses and shortcomings," Yar'Adua said in his inaugural address. "I also believe that our experiences represent an opportunity to learn from our mistakes."
