WASHINGTON (AP) — Democratic presidential candidate Hillary Rodham Clinton has described the shootings as an episode of “senseless violence” that she linked to other recent mass shootings.

“It’s terrible when we lose Marines anywhere in the world. But to lose four in Chattanooga, Tennessee is just heartbreaking,” she told reporters after holding her first town hall event in New Hampshire.

Authorities and officials say the Marines were killed in two separate attacks at military facilities in Chattanooga.

“I hope that we can find a way to stop this kind of violence that is stalking our children and people in study and people who wear the uniform of our country,” Clinton said.
