The marines were assigned to anti-piracy duty aboard an Italian oil tanker off India`s coast at the time of the shootings. One marine has been allowed to travel home for medical treatment, while the other remains in India.
Italy says the shooting occurred in international waters and that the case should be heard in an Italian court.
India has argued against the suspension of proceedings, saying justice for the fishermen`s families is being delayed "by Italy`s intransigence."
