Two men were killed and another injured when gunfire erupted at a convenience store in north Minneapolis on Sunday morning.

The incident capped a deadly spate of weekend violence in the Twin Cities that police are calling an aberration.

Minneapolis police officers were called to the 2600 block of Emerson Avenue N. at 9:44 a.m. on a report of a shooting, a police spokesman said. When officers arrived at the Emerson Food Market, one man was dead from an apparent gunshot wound.

Two other men were taken to North Memorial Medical Center with gunshot wounds, one in critical condition. He died at the hospital after undergoing surgery.

The third man suffered noncritical injuries.

In the hours after the shooting, dozens of people gathered at a nearby home to grieve the deaths of the men.

By Sunday afternoon, police had one man in custody in connection with the shooting.

Sunday's slayings bring the total to five homicides in the Twin Cities this weekend.

Two men were killed and three wounded in separate shootings in Minneapolis on Friday night, following a Friday morning shooting that left a man dead in the street in St. Paul.

On Sunday, the Hennepin County Medical Examiner's Office identified one of the men killed Friday as 32-year-old Liban Mohamed Abdulahi of Burnsville. Officers found his body inside a car in the parking lot behind the Hard Times Cafe in the Cedar-Riverside neighborhood on Friday night. The medical examiner determined that he died of gunshot wounds.

"This weekend has been an anomaly," said Minneapolis police spokesman John Elder. "We look forward to addressing the reasons for this spike in violence."
