A senior US official flying on Secretary of State John Kerry's plane finds anti-Zionist comments by Turkish PM Erdogan "particularly offensive," Reuters reports:

Turkish Prime Minister Tayyip Erdogan's reported comment equating Zionism with crimes against humanity is "particularly offensive" and has a "corrosive effect" on U.S.-Turkish relations, a senior U.S. official said on Friday.

"This was particularly offensive, frankly, to call Zionism a crime against humanity," the senior U.S. official told reporters as U.S. Secretary of State John Kerry flew to Ankara. "It does have a corrosive effect (on relations)."

"I am sure the secretary will be very clear about how dismayed we were to hear it," the official, who spoke on condition of anonymity, added.
