The International Criminal Court (ICC) has fined the former vice-president of the Democratic Republic of Congo, Jean-Pierre Bemba, $350,000 (£266,000) for witness tampering.

He has also been sentenced to 12 months in prison, but has been told he won't need to serve the sentence because of time already spent in jail.

The ICC overturned the conviction of the one-time rebel leader three months ago on charges of war crimes and crimes against humanity, after he had spent a decade in detention.

But he was found guilty of bribery, corruption and of coaching 14 defence witnesses.

Bemba wants to stand in DR Congo's presidency in elections due later this year, but the country's courts have barred him from contesting the poll because of his conviction.
