A devastating Texas explosion at a fertilizer plant was delivered through international breaking news Thursday (11:00 a.m. Australia). It has resulted in at least two confirmed deaths, so far. About three firefighters may have been killed, too. Details are still hazy as of late-night Wednesday local time. The main concerns now are the relocated residents, the scores injured, and the possibility of a second blast.

Texas Explosion: Scores of residents injured, Firefighters killed - 10 Things We Know

1. A powerful blast came after a fire erupted in a fertilizer plant, which is situated on the edge of a residential town in West, Texas.

2. West mayor Tommy Muska has been quoted as saying, "[the resulting scene looked] like a nuclear bomb went off."

3. The Texas explosion was the effect of a fire that developed early in the evening. EMS personnel and firefighters were quick to respond. The massive blast erupted while the firefighters were in action. Some of these firefighters remain unaccounted for, as of late night in West Texas.

4. West Emergency Medical Services director Dr George Smith told the local KWTX station tens of people may have died from the very strong blast. "We have two EMS personnel that are dead for sure, and there may be three firefighters that are dead," he told the CNN. However, authorities are wary against releasing specific updates while details remain unclear.

5. West residents were asked to evacuate as scores of injured were rushed to hospitals in Waco. A specific number of the injured has yet to be reported, but it is expected to go above 100.

6. Health officials are concerned about the fertilizer called Anhydrous Ammonia, which is a huge health risk to those who would be exposed to it in high concentration. The gas goes to the ground once exposed, bringing more danger to more people.

7. CNN reported the West explosion registered a magnitude 2.1 tremor even as the blast was over ground. Residents about 40 miles away have reportedly felt the tremor caused by the massive Texas explosion.

8. Texas Department of Public Safety, D.L. Wilson told reporters during a briefing, the explosion was "massive, just like Iraq."

9. An estimated 50 to 75 houses were damaged in the blast. Part of the blast-affected area is a nursing home with about a hundred persons in, an apartment complex with about 50 units, and a school.

10. Aircrafts flying below 3,000 feet are asked to stay away the 3-mile radius from the blast scene. A second blast remains possible, even as the fire has been declared under control. Cause of fire remains unknown.
