Two people have died and nine others are injured after a mass shooting at Brown University in Providence, Rhode Island, on Saturday, Mayor Brett Smiley announced.

Smiley made the announcement at a press conference alongside state officials including Gov. Brad McKee (D-RI), who called the shooting “unthinkable.” Eight of the injured are in critical, but stable condition, according to the university. A ninth individual was later reported injured by bullet fragments, though they are expected to fully recover.
