A 15-year-old boy dead and three injured, including a police officer: this is the provisional toll from the shooting in Washington DC, near the Moechella Music Festival, in an area considered the African-American heart of the capital full of restaurants, bars and shops.
The police had reported an earlier incident to the evening, after a fight broke out, then a second, when people began to scatter and some people were trampled.
The authorities had thus decided to end the concert for safety reasons.
The festival included a series of concerts on the occasion of Juneteenth, the new national holiday that commemorates the end of slavery in the USA.
In another shooting, also in Washington DC, a 16-year-old was killed.
