Nigeria Closes All Land Borders Ahead of Tuesday's Gubernatorial Elections Kim Lewis April 22, 2011 Policeman stand guard as suspected rioters await a court hearing in Kaduna, Nigeria, April 20, 2011 Photo: AP Policeman stand guard as suspected rioters await a court hearing in Kaduna, Nigeria, April 20, 2011 Nigeria's government has stepped up security in the southeast and closed all land borders ahead of Tuesday's gubernatorial election. Tension remains high as opposition parties continue to accuse the ruling People's Democratic Party [PDP] of rigging the presidential election held on April 16^th. The PDP denies the charge, but the opposition says it will make it impossible for the party to win the governorship election. Violence erupted in northern areas following the vote While security has increased countrywide, there are some southeast states that will be watched especially closely. One of them is Abia, where the governor, once a member of the opposition, has now joined the PDP. Another is Imo State, where the opposition accuses the governor, also a former opposition party member, of intimidating opposition candidates -- a charge he denies. Two other states to watch are Enugu, where the current governor, a PDP member, has lost favor in the eyes of many who once supported him, and Bayelsa, home state of President Goodluck Jonathan, where the ruling party generally has widespread support but where, also, those who disagree with him will likely not support the PDP candidate for governor. Citizens are making preparations for the election despite the observance of Easter weekend. Many are going from the towns to their home villages to register to vote . They are encountering a strong security presence, with armed soldiers guarding the entrances to cities. VOA reporter Chinedu Offor is on assignment in Nigeria.
