Sky News and ITN have also been invited to take part in the negotiations, which follow the deaths earlier this year of BBC driver Abed Taboush and APTN and Reuters freelancers Miguel Gil Moreno and Kurt Schork.
The talks were prompted by a meeting at the London-based Freedom Forum last week. Members of Moreno's family unveiled a list of suggestions, entitled Setting the Standard, for universal guidelines on frontline reporting.
They included mandatory safety training for freelance, contract and staff reporters working in conflict areas. Moreno's brother, Alvaro, said broadcasters and agencies had to change, 'stop talking and just do things'.
