More than 100 American professors and teaching staff at Columbia University have called for five American companies to withdraw their investment in Israeli jails over "breaches of human rights in the occupied Palestinian territories," the website of Israeli TV channel 7 said. The companies that invest money from the American Pension Fund included Motorola, a company which manufactures unmanned aircraft vehicles, and a company that supplies Israel with apache and F16 fighter jets. The website attributed the reason for this campaign to Israeli negligence for the frustration of Americans towards Israeli policies in the occupied Palestinian territories.
