Several gorillas at a zoo in the US are thought to have contracted coronavirus.

Primates at the San Diego Zoo are displaying symptoms of the diseases in a similar manner to humans as they are coughing and suffering with congestion.
It is thought that the infection has spread from an asymptomatic staff member despite measures in place to protect the animals.
Lisa Peterson, the zoo's executive director, said: "Aside from some congestion and coughing, the gorillas are doing well.
"The troop remains quarantined together and are eating and drinking. We are hopeful for a full recovery."
The outbreak is believed to be the first cases amongst captive primates in the US and possibly the world although minks and tigers have previously been infected with COVID-19.
Vets are closely monitoring the gorillas, who have been given vitamins, fluids and fruit but no specific treatment for the disease.
