WYNWOOD (CBS4)- Fire officials had to shut down an apartment complex leaving approximately 50 residents displaced after an early morning fire Saturday.

According to Ignatius Carrol with Miami Fire Rescue, the fire occurred at a two-story apartment complex with 42 units at 3333 NW 5^th Avenue in Wynwood.

When fire rescue arrived around 4 a.m. smoke covered the block. Evacuations were made, although several of the residents had already evacuated.

It took 25 minutes to get the fire under control, officials said.

Six people were transported with five of them with burns ranging from minor to severe burns.  One person was transported for chest pain.

There appeared to be an explosion in the unit where the fire originated.

Some residents jumped off the balcony to escape the fire, Carroll said.

Some of the residents were allowed back inside. But officials later shut down the entire building after accessing for smoke and water damage leaving approximately 50 residents without a place to stay.

The Red Cross was on the scene to assist residents.
