At least four students were shot outside a Pittsburgh high school Tuesday in the city's Homewood West neighborhood, authorities said.

Victims were identified as three boys and one girl, according to a report, with three being 15 years old and one 17-year-old, according to a report.

The shooting occurred shortly after Westinghouse Academy 6-12 dismissed students for the day at 2:15 p.m., and all four students were rushed back inside after they were shot.

Emergency medical technicians soon arrived, and the students were rushed to a local hospital, where they are reported to be in stable condition.

Three of the students were transported by ambulances, and one arrived via private means.

"We need a lot of change here in Homewood. Drastically," said Yvette Luckey, a resident in the area. "Put these guns down. Pick up a book."

Democratic Mayor Ed Gainey asked Pittsburgh citizens to pray for the victims and spoke out against gun manufacturers.

"Westinghouse is a community filled with scholars and champions, and I want everyone to know and celebrate their accomplishments and not just focus on the violence we saw today," he said. "It is on all of us to show these students that we love and care for them as they recover from this tragedy."

"For too long, gun manufacturers have been able to avoid any accountability for their role in our ongoing epidemic of gun violence," he added. "Earlier today, I called to change the law that gives manufacturers immunity from lawsuits so we can hold these manufacturers accountable for the innocent lives that have been harmed by their weapons."

No suspects have been identified, and there is an investigation into the shooting.
