The United Nations is investigating anti-Semitic incidents in the UN security service, according to a letter to all security staff obtained by The Associated Press. In one incident, a security guard allegedly drew swastikas on a log sheet knowing an Israeli guard would see them and made Nazi-like salutes to his Israeli colleague. In a separate incident, a female Israeli security employee said she was assaulted while working in Vienna. The UN at large is consistently accused of anti-Semitism, as Arab states frequently use the General Assembly as a pulpit to air opposition to the Jewish state. Israel's Deputy UN Ambassador Daniel Carmon said "those signs of hatred and terror are things of the past and they cannot happen in 2006." But he said that the act of one security guard could not be compared to the larger issue of anti-Semitism at the UN.
