Herzliya, March 13 - Italy is on solid legal ground in seeking international arbitration in the case of two Italian marines charged with killing two Indian fishermen, Foreign Minister Giulio Terzi told reporters in Israel on Wednesday. The marines have been at the centre of a diplomatic row between Italy and India for shooting Jelestine Valentine and Ajesh Binki during an international anti-piracy mission off the southern Kerala coast in February 2012. Already-strained relations between Rome and New Delhi notched up on Monday when the Italian government announced that marines Salvatore Latorre and Massimiliano Girone would remain in Italy and not return to India to face murder charges after being allowed to come home to vote in February's general election. "We have juridically solid reasons to proceed in the direction of international arbitration," Terzi told reporters as he arrived at an international conference organized by the Institute for Policy and Strategy (IPS), an Israeli think tank. "The Indian government is amply apprised of all it needs to know about our reasons, as do many of our partners".
