The Los Angeles Times reports that two adults were killed and two students were injured after a shooting took place in a classroom at North Park elementary school in San Bernardino this morning. Local law enforcement officials are describing the situation as a murder-suicide, the paper reported. Details about the students' conditions weren't immediately reported.

One suspect "was possibly down as well," San Bernardino Police Chief Jarrod Burguan told the LA Times.

From NBC News:

A short time later, police reported the "current threat at North Park ES has been neutralized."

The names and ages of the four people involved were not immediately known.

This is at least the second shooting in San Bernardino to make national news in nearly two years. In December 2015, 14 people were fatally shot at a local developmental disabilities facility.

Violence in the city is skyrocketing, too.

"There were 62 slayings in San Bernardino in 2016 β€” a 41% increase from the year before," the Times reports. "It was the deadliest year in the city since 1995."
