With the Ukranian airspace closed, India on Thursday said it was sending government teams for the land borders of Ukraine to help evacuate Indians in need of assistance in the country that came under Russian attack on Thursday. "The topmost priority is the safety of Indians in Ukraine. PM Modi is going to speak to President Putin. We are in contact with all Indian students, facilitating flights out of Ukraine. Several advisories have been issued to Indians in Ukraine," Foreign Secretary Harsh Vardhan Shringla said at a news conference.
