Tense Nigeria inaugurates president

LAGOS, Nigeria, May 29 (UPI) -- Nigerian officials said Islamic terrorists were believed to be behind a spate of bombings ahead of Sunday's inauguration of President Goodluck Jonathan.

The militant group Boko Haram was strongly suspected of attacks that began after he was elected last month to his first full term as president of the major oil-producing African nation.

Goodluck Jonathan was vice president last May when he stepped in after the death of President Umaru Yar'Adua.

CNN said Sunday Jonathan hails from Nigeria's predominately Christian south, which hasn't set well with the Muslim north. There have been allegations of election fraud, and Jonathan last week had to warn Nigeria it was flirting with a repeat of its disastrous civil war if the post-election violence continued.
