One woman was killed and two children injured when the remote-controlled drone came down on houses near to the capital's main stadium.

"It was coming in to land when we lost contact with it. We don't know if it was a technical fault or if it was shot down like the last one," EUFOR's Lieutenant-Colonel Thierry Fusalba told Reuters news agency.
The final round of voting between President Joseph Kabila and former rebel chief Jean-Pierre Bemba is scheduled to take place on 29 October.
