At least two students were wounded in a shooting at a high school in southeast Maryland Tuesday morning, the St. Mary’s County sheriff’s office confirmed. A third individual, who has been identified as the gunman, was also wounded. Latest accounts say there are no fatalities.

All three of the wounded have been identified as students, including the shooter. St. Mary’s County Sheriff Timothy K. Cameron said that a female student and a male student were shot by the gunman, before the school's resource officer [SRO] confronted the shooter.

“As soon as the shots were fired, the SRO was notified by staff and students and quickly engaged the shooter,” Cameron said, according to The Washington Post. No details regarding how the shooter was wounded or the level of injuries inflicted on the two victims have been released.

Authorities say the situation is contained. "The scene is no longer active," said Cpl. Julie Yingling of the St. Mary's County Sheriff's Office.

Special agents from the ATF's Baltimore office are en route to the reported shooting, as are agents from FBI's Baltimore field office, CNN reported.

"The school is on lock down," the school district said, and the incident has been contained, according to CNN. "The Sheriff's office is on the scene; additional information to follow," the statement said.

This is a developing story.
