WASHINGTON, Oct 30 (Reuters) - The partition of Iraq would lead to ethnic cleansing and sectarian killing on a mass scale, Saudi Arabia's ambassador to the United States said on Monday as he warned the United States against leaving Iraq abruptly. "To envision that you can divide Iraq into three parts is to envision ethnic cleansing on a massive scale, sectarian killing on a massive scale," Prince Turki al-Faisal said as he answered questions after a Washington speech. "Since America came into Iraq uninvited, it should not leave Iraq uninvited."
