DR Congo elections: Sunday voting may be delayed

An official from the electoral commission in the Democratic Republic of Congo says Sunday’s elections might be delayed due to technical difficulties.

Earlier, police fired tear gas at a crowd of rock-throwing supporters of opposition presidential candidate Martin Fayulu in the capital, Kinshasa.

The violence came after a ban by the city’s governor on all political gatherings.
