Since March 2015, Yemen has been gripped by war pitting the Houthi group, backed by troops loyal to ex-President Ali Abdullah Saleh, and the internationally recognized Hadi government, which is backed by Saudi Arabia.
Saudi Foreign Minister Adel al-Jubeir said he hoped the United Nations would persuade parties in the conflict to come back to the negotiating table. He said Houthis would have to "come to their senses" and agree that Yemen was free.
The United States and Britain called on Sunday for an immediate and unconditional ceasefire in Yemen to end violence between Houthis and the government.
