The U.N. Security Council has passed a resolution imposing an arms embargo on Houthi rebels in Yemen. U.S. Ambassador Samantha Power said the measure targets those stoking Yemen’s violence.

Samantha Power: “The United States strongly supports the adoption of today’s resolution, which imposes consequences on the Houthi and former President Saleh, demands that the Houthi cease military operations, and calls on all sides to once again return to the negotiating table. The imposition of a global asset freeze and travel ban on Ahmed Ali Saleh and Abdul-Malik al-Houthi, as well as a targeted arms embargo, shows that this council will take action against those who continue to undermine efforts toward reconciliation.”

Several Yemen analysts say the measure could intensify the siege of Yemen, which has choked off its economy and denied vital supplies to a country in crisis.
