US rocked by three separate mass shootings over Easter weekend

Two teenage boys were killed and eight other people were wounded after gunfire erupted at a party in a short-term rental home in Pittsburgh early Sunday, one of at least three mass shootings across the US on Easter weekend.

In Pittsburgh, police said equipment that detects gunfire prompted officers to go to an address on Suismon Street where at least 10 people had been shot about 12.30am Sunday.

First responders brought several of the victims to a hospital, including two 17-year-old boys whom doctors later pronounced dead. Others who were shot but survived took their own rides to the hospital.

The short-term rental provider Airbnb issued a statement saying the person who had rented the home had now been banned from using the service for life.

Investigators determined the violence broke out at a party being thrown at a short-term rental, which drew roughly 200 guests who were mostly younger than 18, police said in a statement.

The violence in Pittsburgh and South Carolina came as many American Christians prepared to attend church to worship on Easter Sunday. They also occurred after at least two other high-profile shootings elsewhere in the US.

A shooting in downtown Sacramento on 3 April left six dead and 12 injured. Another, on Tuesday, left 10 shot on a New York City subway.

Police have arrested suspects in both the Sacramento and New York City shootings.
