Russian officials on Thursday pressured an independent panel of United Nations experts to remove embarrassing material from a report on North Korean sanctions violations, according to a top American diplomat.

“Russia can’t be allowed to edit and obstruct independent U.N. reports on North Korea sanctions just because they don’t like what they say,” Nikki Haley, the U.S. ambassador to the United Nations, said Thursday evening. “We’ve seen the original report and we know the truth — the panel should do the right thing and release it.”
