Canada's Supreme Court on Friday struck down key portions of a law that effectively criminalized prostitution by banning brothels and soliciting on the streets, declaring this disproportionate.

U.S. President Barack Obama Friday gave the Pentagon a year to fix the scourge of sexual assaults that have sparked calls for commanders to lose the power to adjudicate such crimes.

Lawyers for Pakistan's former president Pervez Musharraf said Friday a treason charge levied against him was politically motivated and that he would face a "show trial", urging the U.N. to intervene.
