Tsvangirai is Zimbabwe's new PM

Zimbabwe's opposition leader Morgan Tsvangirai has been sworn in as prime minister in a unity government with President Robert Mugabe.

Mr Tsvangirai won the first round of last year's presidential election, but refused to take part in a run-off in protest against attacks on his supporters.

At a rally after his swearing-in, the new prime minister said he wanted to stabilise the economy, and he called for an end to political violence.
