A shooting in Houston, Texas has resulted in 6 people sustaining injuries  after the shooter opened fire at a southwest Houston shopping center this morning, according to the police.

The scene is now contained, but residents have been asked to avoid the area.

The shooter was described as an African-American and carrying a revolver. Police shot and killed him, according to ABC13 and FOX26.

The shooting has started about 6:20 a.m. local time. A witness told local ABC13 channel that he heard about 100 "steady gunshots" being fired.

"We do not have a count at this time as to how many people have been shot," police said. Earlier, ABC13 reported at least seven people were injured, while KHOU11 says at least six were taken to the hospital.

Victims were lying on the ground, with multiple gunshots initially reported from the scene.

A fire official said some people were shot while inside their cars and the conditions of those wounded were varied. Several people were hit with glass fragments from shattering car windows.

Those who were wounded in the attack were being transported to area hospitals, the HPD tweeted.

"We have several with extremity injuries," an official told reporters. "We have a couple that are more serious."

One witness told ABC13 the shooter fired three or four shots into the front window of her car and also shot the side window of the vehicle. Initial reports indicated seven people were hurt before police reduced the number to six.

Eduardo Andrade, 42, told The Houston Chronicle that two bullets struck his vehicle.

"As I was driving by Law Street I suddenly heard a big explosion," Andrade said. "I covered myself, accelerated and tried to get out of there. I did not know if someone was following me or trying to shoot me."

Andrade added: "I felt the hot air."

Police scanners reported at 6:30 a.m. that a male suspect was firing on vehicles with a revolver, according to ABC13.

At a certain point, a vehicle on Law Street was surrounded by police and a bomb squad was reportedly called in.

Numerous ambulances arrived at the scene. Weslayan Street was briefly closed.

Approximately 20 emergency responders are at the scene, a member of the fire department told ABC13.

A triage area has been set up in a parking lot.

The surrounding stores are usually busy at this time, according to local media.

"At this time, the shooting scene is believed to be contained, but residents are asked to please avoid the area of Weslayan Street between Westpark Drive and Bissonnet Street as it is still an active response and investigation scene," police said.
