Philadelphia, Tennessee and Michigan shootings leave at least nine dead and 27 wounded

Gunfire erupted Saturday night in Philadelphia's downtown area and near a Chattanooga nightclub and north-west of Detroit on Sunday morning

Gunfire killed three people and wounded at least 11 in one of downtown Philadelphia's most popular entertainment districts late on Saturday night, hours before separate shootings in Tennessee and Michigan left six dead and at least 16 wounded, authorities said.

The violence erupted as many, including US president Joe Biden, call on Congress to enact meaningful gun control measures, especially in the wake of deadly mass shootings last month in Buffalo, New York, and Uvalde, Texas.
