Zimbabwe's President Robert Mugabe has said the opposition MDC has until Thursday to agree a power-sharing deal, or he will form his own government.

He told state media that they feel frozen at the moment [without a government].

The MDC has rejected the ultimatum and says it will not be "bullied" into signing a deal.

Both Mr Mugabe and MDC leader Morgan Tsvangirai say they won elections earlier this year. The MDC says it was subjected to state-sponsored violence.

At talks mediated by South Africa, the two rivals agreed that Mr Tsvangirai would be named prime minister while Mr Mugabe remained president, but they cannot agree on how to share powers.
