Vester Flanagan, who was believed to have killed two US journalists while they were carrying out a live interview, has killed himself, CNN reports.

Flanagan was being pursued by law enforcement agents at the time of his death, and it is believed that he killed himself.

Reporter Alison Parker and cameraman Adam Ward from WDBJ news were killed earlier today (Wednesday). Flanagan previously worked for WDBJ as a reporter, under the name Bryce Williams. Authorities suspect that today's attack may be related to a workplace issue.
