It Makes a Difference to the Sheep

DOES THAT MEAN THEY'RE TERRORISTS?

Hwang also said that after he heard that some radical South Korean students had formed a suicide squad to try to block his U.S. visit, he tried to meet and talk with them but was unable to because of the opposition of authorities.

“Why do they try to give up their precious lives to prevent a person like me from visiting the United States?" Hwang said.

It isn't clear from the all too brief article what "suicide squad" actually means. Did they plan to kill themselves in protest? (if so, what exactly was the point)? Or, did they plan to stop Hwang with violence even if it meant their own death (i.e. act as suicide bombers)? I suspect the former. Whatever the case, it sounds a bit strange to me.
