HOUSTON: Authorities say a gunman and at least one other person are dead in a shooting in Houston. Police spokesman John Cannon says there were two armed suspects involved.

One was killed and the second was wounded and taken to a hospital. Cannon says the second person killed was found inside a vehicle. The circumstances of the death were not immediately available.

Authorities had urged residents of the west side neighborhood to remain in their homes amid reports of a man firing a weapon. That warning was lifted later Saturday afternoon.

At least one motorist told Houston television station KHOU his pickup truck was hit by a bullet that went through a door.

Authorities have blocked several streets in the area. Cannon describes the scene as an active investigation.

In March this year an ambush-style shooting at a backyard barbecue in the north-eastern US state of Pennsylvania had killed five people.

Four of the victims — three women and one man — died at the scene while another woman succumbed to her wounds in hospital, police said in a statement.
