New Delhi on Thursday refuted Russia's claim of stranded Indian students being held as "hostages" by Ukrainian forces in the war-torn country. "We have not received reports of any hostage situation regarding any student," Indian External Affairs Ministry spokesperson Arindam Bagchi said, adding that they were in touch with the students. "We have requested support of the Ukrainian authorities in arranging special trains for taking out students from Kharkiv and neighbouring areas to the western part of the country," he said in a statement.

On Wednesday, a Russian military spokesperson told the media that Ukrainian authorities "are forcibly keeping a large group of Indian students in Kharkiv who wish to leave Ukrainian territory". Last evening only, the Indian Embassy in Ukraine asked all its nationals to leave the city of Kharkiv, where an Indian student was killed in Russian shelling a day before. Earlier in the day, Moscow's envoy in Delhi said that they would investigate the death of Naveen Shekarappa Gyanagoudar, the 21-year-old Indian medical student. "Russia will do everything it possibly can to ensure the safety of Indian citizens in the areas of intense conflict... and a proper investigation of this unfortunate incident,"  Russian Ambassador-designate Denis Alipov told the local media on Delhi. On Monday night, Prime Minister Narendra Modi ordered four of his senior Ministers to rush to Ukraine's neighbouring countries to help evacuate not only Indians but also foreign nationals stranded in that country. In a statement, the Foreign Ministry had said, "The Prime Minister pointed out that the visit of four senior ministers as his Special Envoys to various nations will energise the evacuation efforts. It is reflective of the priority the government attaches to this matter."
