JERUSALEM (AP) — Former Israeli President Moshe Katsav drove off Wednesday to a prison in central Israel to serve a seven-year prison sentence for rape, but not before insisting he was innocent and accusing the state of Israel of "executing" him and "burying a man alive." Israeli television showed Katsav leaving his home in the southern town of Kiryat Malachi and getting into his car to drive about an hour to Maasiyahu prison in central Israel, where he will begin serving his sentence. Katsav was convicted in December of raping a former female employee when he was a Cabinet minister and of sexually harassing two other women when he was president from 2000 to 2007. Israel's Supreme Court rejected his appeal of his conviction and prison sentence.
