One hurt in restaurant blast

One person has been taken to hospital and others are feared injured after an explosion at a pizza restaurant.

Lothian and Borders Police say the explosion took place at Mamma's American Pizza Company in Edinburgh's Grassmarket.

A spokeswoman says it is believed the explosion may have been caused by a gas canister.

The police spokeswoman added that staff were in the restaurant opening up at the time of the incident.

She says one person has been taken to Edinburgh Royal Infirmary with burns, while it is likely other staff members will be treated for shock.

She said: "It's very early days at the moment and we are on the scene.

"The main priority is accounting for all the staff and making sure they get medical treatment."

It is not yet known how much damage has been caused to the restaurant and whether other buildings may have to be evacuated.
