From wikipedia:
In a controversial Guardian special report published in 2006, McGreal, who has covered both apartheid South Africa and Israel in his career, compared the two and alleged numerous similarities, citing the United States Department of State's annual human rights report for 1999.[1] Among other claims, McGreal alleged that Israel's Population Registration Act is similar to an apartheid era South African Act of the same name. The latter categorized South Africans according to racial definitions in order to determine who could live in what land. McGreal alleges that the Israeli act "serves a similar purpose by distinguishing between nationality and citizenship. Arabs and Jews alike can be citizens, but each is assigned a separate 'nationality' marked on identity cards(either spelled out or, more recently, in a numeric code), in effect determining where they are permitted to live, access to some government welfare programmes, and how they are likely to be treated by civil servants and policemen."[2]
Extensive responses to McGreal's allegations were offered by several media watchdog organizations, including the Committee for Accuracy in Middle East Reporting in America,[3][4][5] the Britain Israel Communications and Research Centre, [6] Engage,[7] and Honest Reporting,[8] which viewed his claims as false and defamatory. The Guardian's letters editor reported that "more than 100 letters on the subject had been directed at the page, with roughly three endorsing the decision to deal with the subject, to every two against, most of the latter rejecting any apartheid analogy."
