Obviously, we're still waiting to see what that will look like.

But there's a good chance we see targeted airstrikes against ISIS strongholds or ISIS leadership throughout Syria.

Trump has not been shy about very aggressive responses to these kinds of situations.

Kevin, thanks for reporting.

Two Brown University students are dead after a gunman opened fire inside a classroom on Saturday.

Yeah, this was a horrifying incident that lasted all throughout Saturday night and into Sunday morning.

It began around four in the afternoon on Saturday.

A gunman entered Brown University's Barrison-Hawley Engineering Building, killed two students, and injured nine others while they were studying for an economics final.

The gunman initially seemed to get away from law enforcement.

Students sheltered in their dorms and classrooms, wherever they thought that they could find a safe space.

Brown tennis player Chloe Chin locked herself in a closet for hours.

Brown University sent a couple of alerts out over an active shooter on campus.

Around 6.30 in the evening, authorities held their first press conference.

Information was limited.

They said two people were dead and the shooter had not yet been found.

Over the next few hours, Brown continues to warn students to stay sheltered.

At 9.30, authorities gave a second press conference and Providence Mayor Brett Smiley confirmed that the attack wounded nine and killed two.

Police released a video of a man dressed in dark clothing who they say is a person of interest in the attack.
