Blast hits beer parlor in Nigeria — third one on day of inauguration

Nigerian President Goodluck Jonathan was re-elected in April to serve his first full term.

(CNN) — A third explosion rocked part of Nigeria on the day of President Goodluck Jonathan’s inauguration, authorities said Monday.

A blast at a beer parlor in the northern city of Zaria took place Sunday night, injuring two people, said National Emergency Management Agency spokesman, Yushau Shauib.

Authorities previously reported a bomb in Bauchi, east of Zaria, and an explosion at a beer hall in Zuba, on the outskirts of the Nigerian capital of Abuja.

In the Zuba blast, two people were killed and 11 others are hospitalized, Shauib said.

A casualty toll in Bauchi was not immediately given. That blast took place at Mammy market, Shauib said.

In recent weeks, the African nation has been rocked by a series of bombings thought to be engineered by Boko Haram, an Islamic group that has challenged Nigeria’s government.

Explosions in Nigeria’s northeastern state of Borno killed a few and wounded dozens in late April in the days leading up to the national governorship elections. Police described the attacks as attempts to intimidate voters who had picked Jonathan.

Northern Muslims in some areas charged that the presidential election was rigged. Armed protesters in the region took to the streets chanting the name of former military ruler Muhammadu Buhari, the main opposition front-runner.

This is Jonathan’s first full term. As vice president, he took over the presidency in May 2010 upon the death of then-President Umaru Yar’Adua, who had suffered from a heart condition.
