Dominique Strauss-Kahn broke his silence four months after a New York hotel maid accused him of sexual assault, calling his encounter with the woman a “moral failing” he deeply regrets, but insisting in an interview on French television Sunday that no violence was involved.

Strauss-Kahn, the former head of the International Monetary Fund and a one-time top presidential contender in his native France, also denied using violence against a French writer who claims he tried to rape her in a separate 2003 incident.
