Washington, Nov 24 (TIWN) At least 10 people were killed when a gunman opened fire at a Walmart in Chesapeake located in the US state of Virginia, police said on Wednesday.

The mass shooting in the city of Chesapeake comes just before Americans celebrate the Thanksgiving holiday and follows a weekend gun attack at an LGBTQ club in Colorado that left five people dead.

"Chesapeake Police confirm 7 fatalities, including the shooter, from last night's shooting at Walmart on Sam's Circle," the city confirmed on its Twitter account.

Chesapeake Police Department officer Leo Kosinski had earlier told reporters that there had been "multiple fatalities" at the megastore, which local media reported was busy with holiday shoppers.
