US Secretary of State John Kerry has announced a ban on the issuing of US visas to foreigners implicated in wartime sexual violence.
"No one at the highest level of military or governance who has presided over, or engaged in, or knew of, or adopted these kinds of attacks is ever going to receive a visa to travel into the United States of America from this day forward," Kerry said during talks with his British counterpart, William Hague.
Hague applauded Kerry's announcement.
"The shattering of impunity ... is the crucial ingredient so that people know they will not get away with it," he said.
He added that in spite of increasing awareness of the issue, "what had been missing was some of the largest governments in the world throwing their weight against it".
