Italian marines case: India talks tough

India has asked the Italian government to send back four marines witnesses to India in Italian marines case. India has also refused Italy's option to send the National Investigation Agency (NIA) team to Italy to questioned the four marines, who were onboard the Italian vessel Enrica Lexie when their colleagues Massimiliano Latorre and Salvatore Girone allegedly shot dead two Indian fishermen on February 15, 2012. India has conveyed to Italians that more delay in the trail will affect Latorre and Girone, who are currently lodged in India.
