U.S. Ambassador to the United Nations Samantha PowerSamantha PowerObama's UN envoy apologizes for not recognizing Armenian mass killings as genocide New US approach to Syria a welcome sight to many in region Trump’s response to Syrian bloodshed lifts the stain of American inaction MORE said Thursday that she condemned as "abhorrent" comments by Iranian leader Ayatollah Ali Khamenei, who called Israel a "rabid dog."
Powers's comment came amid criticism that a senior U.S. official on Wednesday had stopped short of condemning the comments amid high-stakes negotiations over Iran's nuclear program.
In an address to the Basij paramilitary force on Wednesday, Khamenei made the disparaging comment toward Israel and accused the U.S. of launching its nuclear attack on Japan after the country had already surrendered in World War II.
Asked about the comments later in the day, a senior U.S. official stopped short of a condemnation.
“Of course I don’t ever like it when people use rhetoric that in any way talks about the U.S. in ways that I find very uncomfortable and not warranted whatsoever,” the official told reporters in Geneva, according to BuzzFeed.
The official's remarks stood in contrast to a statement from France, which condemned the remarks and said they complicated nuclear talks.
Khamenei did express support for the nuclear negotiations in Geneva, which continue Thursday.
