The last four cars in the cavalcade ferrying security, protocol and a cameraman collided when the one moving in the front suddenly developed some problem, an official said.
The President drove to Uppsala University where he spoke on "Tagore and Gandhi: Do they have Contemporary Relevance for Global Peace?", while the occupants of the vehicles involved in the mishap were rushed to a nearby hospital.
The protocol officer who sustained minor injuries was discharged after first aid.
All of them joined the delegation of the President who left for Belarus at the end of his three-day visit to Sweden.
