At least six people were wounded Monday when a gunman opened fire on passing vehicles in southwest Houston, police said.

The suspected gunman was fatally shot by officers who responded at the scene, police said.

Police tweeted they were on the scene of an "active shooter incident" north of West University, then tweeted that a suspect "has been shot by our officers." Later they confirmed the shooter had died.

There were no reports of other gunmen, police said. The Houston Fire Department said ambulances transported at least 6 people from the scene, one in critical condition.

Several ambulances and other emergency vehicles responded to the Randalls grocery store shopping center shortly at about 6:30 a.m. local time. Bellaire, West University and Houston emergency responders worked together to take the victims to the hospital.

The Houston Police Department bomb squad was checking the suspect's vehicle, and several blocks in the area were closed off. Some vehicles in the area were parked with bullet holes or shattered windshields.

"Please join me in keeping the victims of the shooting in Houston this morning in your thoughts and prayers," Gov. Greg Abbott tweeted.
