Yemen's Houthis have demanded $51 billion from Saudi Arabia and official recognition as Yemen's rulers in exchange for an end to hostilities, the WSJ reports. The Houthis said the money should compensate for years of airstrikes and a blockade by Saudi Arabia. Saudi Arabia's crown prince, Mohammed bin Salman, is reluctant to negotiate without achieving military success, but also fears that sending more ground troops could lead to more casualties and a domestic backlash.
