Polls open in Sierra Leone's runoff presidential vote

Polls have opened in Sierra Leone's runoff presidential election.

Voting is peaceful and the turnout is lower than in the first round on March 7. Security is tight in the West African nation.

The vote had been set for Tuesday but was delayed after a ruling party member filed a court challenge alleging irregularities in the first round and a temporary injunction was issued, stalling preparations. It was lifted early this week and the election commission asked for a few more days to prepare.

The opposition Sierra Leone Peoples Party, which took 43.3 percent to the ruling All Peoples Congress party's 42.7 in the first round, has not held the presidency since 2007.

President Ernest Bai Koroma has served two terms and is barred by the constitution from running again.
