Students at the University of North Carolina at Chapel Hill resorted to climbing out of windows and jumping out of buildings after bullets started flying on campus.

In new video from Monday's deadly school shooting, you see college students fleeing a building through an open window ... dropping their book bags to the ground and then jumping to safety.

Amid spreading reports of an active shooter on campus, the students are left to climb out a window and onto a ledge, where they take a few steps to find a soft spot to land ... jumping down into some bushes.

The university shots were fired inside a chemistry lab Monday afternoon around 1 PM and the suspect, Tailei Qi, a UNC doctoral student, was taken into custody around 2:30 PM after a faculty member was shot dead.

Campus police say there is no longer an immediate threat ... and the video shows just how scary the situation was as it unfolded.
