The leader of Yemen’s Houthi rebels, Abdel-Malik al-Houthi, vowed to defy the Saudi-led campaign on Sunday, saying that Saudi efforts to “humiliate” his country were doomed to fail.

[New York Times]

IRAN NUCLEAR TALKS

The House Foreign Affairs Committee will hold a hearing this week on verification of an emerging deal with Tehran, following last week’s Senate panel vote on an Iran bill allowing congressional review of a final accord. [Al-Monitor’s Julian Pecquet]  Sen. Ben Cardin argued that the new bill places President Obama “in a stronger position” in the negotiations with Iran, speaking on CNN’s “State of the Union.”  Meanwhile, Sen. Lindsey Graham said on “Fox News Sunday” that there is no chance Congress will approve the “deteriorating” nuclear deal.

President Obama said that the specifics of how sanctions are lifted will be drafted in a way that allows Tehran “to make a presentation to their body politic that is more acceptable,” while also addressing all of the administration’s concerns. [Politico’s Sarah Wheaton]  The Wall Street Journal editorial board writes that these comments, made on Friday, offer further proof that Obama keeps giving into Ayatollah Ali Khamenei’s demands, paving the way to a deal that “confers Western blessing on Iran as a nuclear-threshold state.”

Israeli analysts have expressed shock at President Obama’s “stated openness” on the Iranian demand for the immediate lifting of economic sanctions and his comments on Moscow’s proposed missile sale to Iran, reports the Times of Israel.
