At least 13 people were injured in a suspected gas explosion in a resteraunt in the Centro Internacional De Macau on early Tuesday morning, firefighers said.

Seven of the eight people who were injured and sent to hospitals have been discharged, the firefighters added.

The incident occurred at around 7 a.m. local time in the morning and even the glass of the main entrance of the Hotel Golden Dragon nearby were smashed.

The area has been cordoned off and the firefighters were clearing the site.

Firefighters said they suspected that gas leakage led to the blast and some gas cylinders were found on the scene.
