Ecuador chooses president during wave of violence

Ecuadoreans are voting in the run-off of a presidential election that has been overshadowed by a crime wave which has turned the country into one of the most violent in the region.

The first round of the election was held just days after presidential candidate Fernando Villavicenio was shot dead in the capital, Quito.

Seven suspects were arrested in connection with his assassination, but have since been killed in jail.

Security is voters' main concern.
