UPDATE 2:20 p.m.:
The Houston Fire Department confirmed six construction workers were injured and taken to the hospital on Wednesday.
This appears to be a pressure situation with a tankless water heater, where a natural gas line exploded, causing the windows to blow out and a fire to flare up quickly.
The building did not collapse and all injuries to the six construction workers are burns and lacerations.
ORIGINAL 12:26 p.m.:
Multiple people were injured after an explosion at a high-rise in downtown Houston, the Houston Fire Department says.
HFD says crews responded just after 11 a.m. on Thursday to a reported fire at a high-rise fire at 1319 Texas Avenue.
Multiple people have been reported injured. The fire department believes everyone who was injured were construction workers, as the building is a Holiday Inn that is currently under construction and not yet open to the public. The site says it plans to open in December.
Due to the reported explosion, HFD HAZMAT has been added as a precaution.
This is a developing story and will be updated as more information is released.
