Police stood guard Thursday afternoon outside a building on the campus of Old Dominion University in Virginia, where authorities say the shooter killed one person and injured two others.

Authorities are investigating a shooting at a Virginia college Thursday that left one victim dead and two injured as an act of terrorism, FBI Director Kash Patel said.

The students "subdued him, and rendered him no longer alive", she said, adding that he was not shot, without providing further details.
