East Timorese President Jose Ramos-Horta has alleged Indonesian television station Metro helped fugitive rebel Alfredo Reinado travel to Indonesia for an interview in May 2007.
Reinado was killed during attacks on February 11 which targeted Dr Ramos-Horta and East Timor's Prime Minister, Xanana Gusmao.
Dr Ramos-Horta says there is strong evidence that with the help of authorities in West Timor, Metro organised false documents for Reinado to travel to Indonesia for the May 23 interview.
He questioned how the rebel leader, who had a warrant issued for his arrest, managed to enter Indonesia after the President specifically requested that the border be closed following an attack by Reinado on a border post.
He said the actions of the journalist who organised the interview, Desi Anwar, breached fundamental codes of ethics and violated East Timorese law.
He said Metro and other Indonesian elements' actions contributed to the attempt on his life and he will not rest until the truth of their involvement with Reinado is uncovered.
Dr Ramos-Horta arrived home this week after more than two months of treatment in Darwin for injuries he sustained in the assassination attempt
