A UN human rights investigator has been sent packing from Zimbabwe, after being detained overnight.

Manfred Nowak, an Austrian academic who works as the UN Human Rights Council's special rapporteur on torture, had been invited to the country by Morgan Tsvangirai, Zimbabwe's prime minister.

He was denied entry by the Zimbabwe's foreign ministry, heaping further pressure on Tsvangirai's power-sharing deal with President Robert Mugabe.

From Harare, Haru Mutasa reports.
