Swedish police say the motorcade of visiting Indian President Pranab Mukherjee was involved in a traffic accident that left nine people with minor injuries.

Uppsala police spokesman Christer Nordstrom says the president and other top dignitaries were unharmed in Tuesday's accident, which happened as Mukherjee was heading to an event at Uppsala University.

Nordstrom said "shortly after they left the highway, four cars in the motorcade crashed into each other. How it happened I don't know."

Mukherjee was visiting Uppsala, about 65 kilometers (40 miles) north of Stockholm, on the final day of his state visit to Sweden.

The president's program was not affected by the crash and he left the country later Tuesday.
