A demonstrator cries during a protest against the killing of Excalibur, the dog of Spanish nurse Teresa Romero who is the first person to contract Ebola outside of Africa, and the handling of the Ebola crisis, in Madrid October 11, 2014. Health authorities on Thursday put down the dog, a labrador-type breed, who lived with the nurse and her husband in a suburban Madrid flat, saying it posed a biological risk and there was evidence dogs could carry the virus. Sixteen people were being monitored in a Madrid hospital for signs of Ebola on Saturday, with patient numbers rising as the Spanish government tries to contain recriminations over how it has handled the first outbreak of the disease outside Africa.
