Spanish authorities reported four new patients with suspected Ebola symptoms on Thursday, including a feverish passenger who started shaking on an Air France flight to Madrid and a Spanish priest who had recently been in Liberia.

Three of the cases were in the capital and the fourth in the Canary Islands, where a health source said two other people were admitted to hospital for precautionary monitoring.

The priest, who arrived in Spain on Oct.11, was being taken to hospital after developing a fever, one of the symptoms of the disease, the Spanish government's Ebola committee said.
