Members of a Cuban choir on tour in Canada have defected. “In all, 11 of the 41-member choir managed to flee the hotel between 6 p.m. and 9:30 p.m. on Sunday, when Digna Guerra, the choir’s manager, discovered the absences. In an emergency meeting, she warned the remaining singers that the Cuban government would retaliate against their family members if they tried to seek asylum here.”
