WASHINGTON (Reuters) - U.S. national security adviser Jake Sullivan said on Monday that President Joe Biden's administration did not view the killings of Palestinians in Gaza by Israel in its war with Hamas as a genocide.

Sullivan, speaking to reporters at the White House, said the United States wants to see Hamas defeated, that Palestinians caught in the middle of the war were in "hell," and that a major military operation by Israel in Rafah would be a mistake.
