India on Wednesday said it will take further action on the Italian decision not to send back the two marines accused of killing two Indians after awaiting Rome's reply.
"It (the Italian move) is unacceptable. We are awaiting the response of the Italian government. We have made our position very clear," foreign secretary Ranjan Mathai told reporters in New Delhi.
"Further course of action will be taken after their response," he said.
The government on Tuesday told Italy "in the strongest terms" that it was obliged to ensure the return of the two marines facing trial in India for murdering two fishermen off Kerala.
The Supreme Court on Feb 22 allowed Massimiliano Latorre and Salvatore Girone to fly to Italy to vote in the national election.
The Italian government Monday said the marines won't return to India.
