BIRMINGHAM, Alabama - A 57-year-old man was wounded in a morning drive-by shooting in an Ensley neighborhood.

Gunfire erupted just before 11 a.m. in the 2300 block of 16th in Ensley. Residents in the area said there was an exchange of gunfire; police said bullets were fired from two weapons but it wasn't immediately clear if the wounded man fired back at his assailant.

The victim and others were sitting in lawn chairs when police and neighbors say a car pulled up, someone got out and starting firing with a shotgun. The victim, whose name hasn't been released, was shot in the leg.

The shooter or shooters fled the scene, possibly in a green Honda Accord. Police said there were at least three men inside.

The victim was taken to the hospital with a non-life-threatening wound, police said.

At least six shots were fired. Shotgun shells and bullets from a handgun peppered 16th Street.

One neighbor, who asked that his name not be used, said the victim and the suspect, in his early 20s, have a long-running feud. The suspect and his friends have been driving up and down the street in recent days.

The suspect, he said, pulled up in front of the victim's house this morning and exited the car. "He came out of there like a track star,'' he said. ""He ambushed him. It's not shocking."

The witness said he believed the feud was over a $20 loan.
