India has dropped a plan to prosecute two Italian marines accused of killing two Indian fishermen under a tough anti-piracy law, a government lawyer said on Monday, offering a chance to end a diplomatic row between the two countries. Italy had strongly opposed India invoking the law, arguing that it would amount to treating the men as "terrorists" and last week it recalled its ambassador to New Delhi in protest against the delay in the two-year-old case. The sailors, part of a military security team protecting a privately-owned cargo ship, say they mistook the fishermen for pirates and fired warning shots into the water during the incident in February 2012, off the coast of Kerala state.
