India is in touch with Iranian authorities to ensure the security and early release of 17 Indian nationals who are among the 25-member crew of a cargo ship seized by Iranian troops, people familiar with the matter said on Saturday. A special forces unit of the Iranian Revolutionary Guard Corps (IRGC) carried out the operation to take control of the container ship MSC Aries in the Gulf of Hormuz, about 80 km off the coast of the United Arab Emirates, according to media reports.
