USA: Who won what in latest elections?

We look at the results from the start of the electoral season in the United States. Voters in New York have elected a Democratic mayor for the first time in 24 years. Meanwhile, the mayor of Toronto in Canada comes clean and admits to smoking crack cocaine. Finally, we look at a turnaround for Colombia’s former crime capital, Medellin. The city, once haunted by drug cartels and violence, is now attracting tourists.
