Pakistan's jailed former prime minister Imran Khan was on Monday charged with leaking classified documents, a prosecutor said. "He has been indicted today and the charge was openly read out," said Shah Khawar of Pakistan's Federal Investigation Agency outside Adiala Jail where Khan is being held. The ex-cricketing superstar was jailed in August for three years over graft but when his sentence was later overturned, he was instead kept in custody on the far more serious charge of sharing state documents.
