New Delhi/Kyiv: At least 13 Indian seafarers are among the 15 crew members stranded aboard a cargo vessel at Ukraine's Chornomorsk port as drone and missile attacks continue in the vicinity of the strategic Black Sea harbour, according to the Forward Seamen's Union of India (FSUI). The sailors' union has warned that the crew is caught in what it described as a "terrible and life-threatening situation", saying those onboard are living in "constant fear of a direct hit at any moment" as hostilities between Russia and Ukraine continue near the port. The latest distress call comes amid a series of attacks involving merchant vessels operating in and around Ukraine's southern coastline in recent days, with the Black Sea emerging as an increasingly dangerous zone for civilian shipping.
