Modi, who arrived here on the second day of his sojourn to France, visited the French Space Agency, CNES, in Toulouse.
"The young usually want selfies. PM @narendramodi obliges Indian students gathered at French Space Agency(CNES)," External Affairs Ministry spokesman Syed Akbaruddin tweeted.
"Took selfies with young friends at CNES. We were all trying to take the best selfie out there," PM Modi tweeted later.
The students told the media that they were not part of the brain drain from India and would be willing to go back to their home country after finishing their studies.
Modi, who arrived in France on Thursday on the first leg of his three-nation tour, held talks with French President Francois Hollande and met business leaders yesterday. His nine-day trip will now take him to Germany and then to Canada.
India on Friday said that it will buy 36 Rafale fighter jets in fly-away condition as both sides also pushed for early conclusion of techno-commercial talks on the Jaitapur nuclear power plant and inked 17 agreements as Prime Minister Narendra Modi held talks with French President Francois Hollande.
The Rafale deal was the biggest takeaway in the talks between Modi and Hollande. India had shortlisted Rafale, made by Dassault Aviation, in a $20-billion deal for purchase of 126 fighter jets for the MMRCA project in 2012. However, the final deal has not been inked.
