MAASIYAHU PRISON (AFP) - Israel's disgraced former president Moshe Katsav on Wednesday began a seven-year jail sentence after being convicted on two counts of rape and other sexual offences. The former head of state, who turned 66 on Monday, entered Ma'asiyahu prison near Tel Aviv shortly after 10.00 am (0800 GMT), an AFP correspondent outside the jail said. He was convicted in December 2010 of two counts of rape, sexual harassment, indecent acts and obstruction of justice after an 18-month trial which included harrowing accusations, and portrayed him as a sexual predator who routinely harassed his female staff.
