Saudi Arabia's U.N. ambassador says a vote on a draft United Nations resolution that would impose new sanctions on leaders of Yemen's Houthi Shiite rebels and the country's former president and his son will likely take place early next week.

Ambassador Abdallah Al-Mouallimi said Russia still wants changes to the text that Jordan had put in a final form for a vote.

Jordan, which holds the Security Council presidency this month, held separate meetings Friday with the five veto-wielding council members, Russia's U.N. Ambassador Vitaly Churkin and others trying to ensure adoption of the resolution.

The final draft would impose an arms embargo on three top Houthi leaders and former president Ali Abdullah Saleh, but Russia has insisted on an arms embargo on all parties to the escalating conflict.
