Dissident threat to Martin McGuinness

All the major news outlets are covering the news that the police have warned Martin McGuinness that there is a threat to his life from dissident republicans. Mr. McGuinness seems relatively un fazed by this (from the BBC):

“It is believed this threat comes from a so-called dissident grouping,” Mr McGuinness said in a statement issued on Friday morning.
“I have spent my entire adult life engaged in the republican struggle to bring about Irish unity and independence.
Throughout that time there have been numerous attempts made to silence me and stop me going about my republican work.”
