Saudi Arabia promises $1.5 billion in aid to Yemen — but it's still bombing the country

Saudi Arabia announced $1.5 billion in new aid for Yemen this week, a move it says is aimed at alleviating the country's humanitarian crisis nearly three years into a Saudi-led military campaign there. But critics, among them a number of Yemenis, have questioned the motives behind the donation, given the Saudis' own role in prolonging the crisis.
