The Kensington Post Office is back open today following a weekend fire. 

The post office, located on McDonald Avenue, was temporarily closed but they were able to open back up around 9 a.m.

Workers say no mail was damaged.

Viewer video shows smoke pouring out of building around 4:30 a.m. Sunday. 

While some of the windows remain boarded up, the post office was taking customers and providing services as normal. 

Workers at the post office say it appears it may have been caused by an electrical issue. 

There were a few workers inside at the time, but they were able to make it out safely.

Two firefighters were taken to the hospital to be treated for minor injuries.
