Tensions mount as Ghana awaits election results

Tension was mounting in Ghana on Thursday over delays in releasing the results of a nail-biting presidential election already tainted by sporadic outbreaks of violence.

The high-stakes race between incumbent John Mahama and rival Nana Akufo-Addo is seen as a litmus test of stability for one of Africa's most secure democracies.

In its latest evening update, the country's electoral agency said that they had received preliminary results from 90 of out 275 constituencies, but only published the results for 25 of them.

Following "possible instances of over-voting" the commission had previously said that the tallies would be subject to extra verification.
