Kerry to admonish Turkish PM Erdogan for "offensive" remark calling Zionism a crime against humanity, official says ANKARA, Turkey A senior American official said Friday that U.S. Secretary of State John Kerry will take Turkey's prime minister to task for "particularly offensive" comments he made this week equating Zionism with a crime against humanity. According to the official, Kerry felt the Turkish-Israeli relationship was currently "frozen." CBS News correspondent Margaret Brennan reports that a U.S. official aboard Kerry's plane to Ankara said the comments could have a "corrosive effect" on U.S. relations with Turkey, and that Kerry intended to express his "dismay" to Prime Minister Recep Tayyip Erdogan over his remark made during a United Nations summit in Vienna. Erdogan's remarks were of significant concern, said the official, as in the past the Turkish-Israeli relationship had demonstrated that a majority Muslim country can have "very positive" relations with the Jewish state. The White House on Thursday also issued a statement condemning Erdogan's remarks. Outrage over the remarks threatens to overshadow Kerry's visit to NATO ally Turkey on his first official overseas trip as secretary of state. He has spent much of his time at the first three stops focusing on the conflict in Syria. Kerry opened his visit to Turkey's capital with a stop at the U.S. embassy where he paid tribute to a Turkish security guard killed in a Feb. 1 suicide attack against the compound.
