MIAMI (Reuters) - World number two Aryna Sabalenka described the death of her former boyfriend as an "unthinkable tragedy" as she commented for the first time on Wednesday on the apparent suicide of Konstantin Koltsov.

The Miami-Dade police department confirmed on Tuesday that they had responded to a call the day before at a Miami resort about reports of a man jumping off a balcony. The police said no foul play was suspected.
