Three people were dead and 14 wounded after a shooting near a bar in Chattanooga, Tennessee, police said on Sunday, adding that two people died from gunshot wounds and one person died from injuries after being struck by a vehicle while fleeing the scene.

Three victims were injured as they attempted to flee and were struck by vehicles, Tennessee officials said, adding several among the injured remained in critical condition.

The incident followed a mass shooting in Philadelphia on Saturday which killed 3 people. It involved multiple shooters.

There were multiple shooters in Tennessee too but Chattanooga Police Chief Celeste Murphy said police believe it was an isolated incident and authorities did not think there was an ongoing public safety threat. Further details on that shooting were not immediately available.

There have been at least 240 mass shootings in the United States so far this year, according to the Gun Violence Archive, a nonprofit research group. It defines a mass shooting as one in which at least four people are shot, excluding the shooter.

U.S. President Joe Biden on Thursday called on Congress to ban assault weapons, expand background checks and implement other gun control measures to address the string of mass shootings.

Chris Murphy, the lead Democratic U.S. senator working on bipartisan gun safety talks, said on Sunday he thinks a package including investments in mental health and school safety and some changes to gun laws can pass Congress.

A broad majority of American voters, both Republicans and Democrats, favor stronger gun control laws, but Republicans in Congress and some moderate Democrats have blocked such legislation for years.
