JITT, WEST BANK - NOVEMBER 11: A Palestinian dips his finger into fresh, warm olive oil as it flows from an olive press November 11, 2007 in the Palestinian village of Jitt in the West Bank. Prices for olive oil, a staple in the Palestinian diet, have risen dramatically this year to about US$6 a litre, up from US$4 a litre last year, which farmers blame on a dismal olive harvest.
