The U.S. is responsible for crimes against humanity regarding Iran and Yemen, Iran’s Foreign Minister said Thursday.

"You know what @SecPompeo? It's the Yemenis themselves who're responsible for famine they're facing. They should've simply allowed your butcher clients—who spend billions on bombing school buses "millions to mitigate this risk"--to annihilate them w/o resisting. #HaveYouNoShame,"Javad Zarif said on Twitter.

On Oct. 30, U.S. Secretary of State Mike Pompeo called for the cessation of hostilities in Yemen. He said in a statement that missile and drone strikes by Iran-allied Houthi rebels against Saudi Arabia and the United Arab Emirates should stop and air strikes by the Saudi-led coalition must cease in all populated areas of Yemen.

"Just as with Yemen, @SecPompeo blames Iran for unlawful US sanctions preventing Iranians’ access to financial services for food and medicine. Naturally, we will provide them for our people in spite of US efforts. But US is accountable for crimes against humanity re Iran Yemen," Zarif said.
