CRI听力:Two Shooting Incidents Happen in the U.S On the Same Day

Authorities in two different US cities are now dealing with mass shootings.

In the city of Detroit, a 20-year old man is dead and nine others have been injured, after someone opened fire during a block party in the city.

Police in Detroit say they're working under the assumption there may be two shooters involved in that incident, and that one individual may have been the intended target.

Of the 9 people hurt in the Detroit shooting, one remains in critical condition.

Meanwhile, in Philadelphia, a similar incident has taken place, with bullets being fired into crowds at a block party in that city.

Philadelphia Police Lieutenant John Walker says they're still trying to figure out what happened.

"we know we have seven people shot at this point, two of those are kids, one is at two years old and one at ten years old. Both are children, both are critical at this point, two year old is shot in the neck. It's been chaos trying to stabilize this two-year-old on scene with the medics. We're just getting things under control. We're going to work through the investigative part of it and try to figure out what actually happened out here"

The mass shootings in Detroit and Philadelphia come just days after the mass shooting at a church in Charleston, South Carolina which left 9-people dead.

That incident has prompted US President Barack Obama to try to reignite debate in the US over gun control.

However, legislation to bring in tougher gun-control laws is unlikely to pass through the Republican-controlled Congress.

Some 12-thousand people a year in the US die in gun-related incidents.
