Rwanda has closed its border with DR Congo in response to the Ebola crisis.
At least two people have died from the virus in the eastern Congolese city of Goma, near the Rwandan border.
Earlier this week a miner became the second person in Goma to be killed by the disease with reports indicating that a third person – believed to be the miner’s daughter – died afterwards.
It is one year today that DR Congo declared what has become its worst outbreak, with more than 1,800 people dead and over 2,700 infected.
The outbreak is the most complicated ever as it is happening in an active conflict zone, BBC Africa correspondent Anne Soy says.
Immigration sources in Rwanda said the border crossing point at Goma was shut on Thursday morning. This was later confirmed by DR Congo officials.
