from the BBC:
Armed militia have raided two camps for people fleeing post-election violence in Zimbabwe, opposition and medical officials have said.
The opposition said several people were killed in Gokwe, north of Harare, but other reports say there was one death.
In Ruwa, near the capital, masked men in army fatigues beat up people who had previously sought refuge at the South African embassy, a witness said.
A BBC correspondent says the raids could threaten moves to share power.
At least eight of those attacked in Ruwa were taken to hospital and about 14 people - mostly from a patrol that camp occupants had organised to maintain security - were missing, the witness said.
About 400 people have been sheltering in local squash courts in Ruwa after being moved on from the South African embassy.
At the G8 summit of the world's leading industrialised countries in Japan, UN Secretary General Ban Ki-moon called on Zimbabwe's political parties to work together to restore the rule of law.

We are saying no party can govern alone in Zimbabwe and therefore the parties have to work together
Tanzanian President Jakaya Kikwete
The US and the UK want the UN Security Council to tighten targeted sanctions against Mr Mugabe and his close allies this week, as well as impose an arms embargo.
But Tanzania's President Jakaya Kikwete, who also heads the African Union, said African leaders favoured some sort of power-sharing government.
The Zimbabwean government blames interference from Western countries for delaying a solution to the country's political impasse.
Justice Minister Patrick Chinamasa said "meddling" by Britain, the US and the European Union was complicating the dialogue between Mr Mugabe's party and the opposition.
The opposition Movement for Democratic Change says 5,000 of its members are missing and more than 100 of its supporters have been murdered since elections in March.
Tens of thousands of people have been displaced.
The MDC accuses the army and ruling party militias of being behind the violence - charges denied by President Robert Mugabe.
Yup. fair and balanced. and without news reporters on the ground, they can't call Mugabe a murderous liar.
