As many as 27 people, including a reported 18 children, were killed Friday after two gunmen reportedly fired hundreds of shots at a Connecticut school.

One gunman is dead after a Connecticut school district went on lockdown following reports of the shooting at Sandy Hook Elementary School. A second gunman is still at large, according to reports.

An eyewitness told World News Tonight anchor Diane Sawyer hundreds of shots were reportedly fired, and dozens of parents are not aware of the whereabouts of their children.

“Due to reports of a shooting as yet unconfirmed, the district is taking preventive measures by putting all schools in lockdown until we ensure the safety of all students and staff,” Newton Public School District secretary of superintendent Kathy June said in a statement.

State police are sending units to Newtown following reports of a shooting at an elementary school.

All public and private schools in the town are on lockdown.

A message on the school district website says that all afternoon kindergarten is cancelled today and there will be no mid-day bus run.
