Meeting ahead of the UN General Assembly with Rashad al-Alimi, head of Yemen's presidential leadership council, Blinken hailed the country's new leader for his "vital" role.

"I think it's fair to say that the truce, whose effects are being felt throughout Yemen, has made a profound difference in improving people's lives, and your own leadership in working to sustain that truce has made a huge difference," Blinken said.
