'Stay out of Congo' - US
The United States has appealed to the neighbours of the Democratic Republic of Congo not to get involved in the rebellion against President Laurent Kabila in the east of the country.
The spokesman said the US was also concerned that Tutsis were being arrested and harassed.
The US appeal came despite Rwanda's denial that its soldiers had invaded the eastern part of the country.
It followed news that the eastern town of Bukavu had fallen to the rebels. Officials in Kinshasa said that the country's third largest city, Kisangani, was still under government control.
Independent sources said the rebels had made significant gains in Goma and Kindu.
A big march in support of President Kabila is planned in the capital, Kinshasa.
Rwanda "not to blame"
The Rwandan president, Pasteur Bizimungu, has denied allegations from Kinshasa that his country was responsible for the unrest.
"There is no reason for Rwanda to be involved in the internal affairs of Congo," he said.
But President Bizimungu did not rule out future involvement.
"If we have serious reasons to be involved maybe we should," he said.
He denied that the unrest was a rebellion by disaffected soldiers in the army.
Foreign Minister defection
Mr Karaha failed to return to Kinshasa from a visit to South Africa earlier this week. Johannesburg newspaper The Star said it interviewed him on Monday, and quoted him as saying he was joining the rebels.
In a phone interview to the Reuters news agency from Goma, Mr Karaha is reported accusing President Kabila of failing to govern.
"In his one year in power he has done more political damage than Mobutu ever did in 32 years," he said.
Mr Karaha, an ethnic Tutsi, has been foreign minister since helping President Kabila take power in 1997.
Meanwhile, Zimbabwe is to organise a regional summit to try and deal with the unrest in Congo and the Great Lakes region in general.
The conference is due to start on Friday afternoon in the resort town of Victoria Falls and carry on until Saturday.
The presidents of Uganda, Rwanda, Tanzania, Namibia, Zambia and the Democratic Republic of Congo are reported to have confirmed their attendance.
But a BBC correspondent in Zimbabwe says there is some doubt as to whether Mr Kabila would risk leaving Kinshasa at such an unstable time.
