Early Tuesday a fire broke out in Beirut’s commercial district.

The third fire in the area within one week. There were no initial reports of injuries.

This is a building under construction known as the oval building in Beirut's markets. What caught fire was the insulation material between the inside and the outside of the building.

Officials say the cause of all 3 fires is unclear. The fire occurred not far from the site of a huge port explosion in August.
