Yemeni officials say Shiite rebels and the internationally recognized government have agreed to begin a ceasefire for a week or two before their next round of negotiations. The officials participated in talks Sunday in Sanaa, the capital, between the rebels and U.N. envoy Ismail Ould Cheikh Ahmed. They say talks are expected to restart next month. The officials said the Shiite rebels, known as Houthis, have agreed to implement a U.N. security council resolution which requires them to hand over weapons and withdraw from territory, including Sanaa. All officials spoke on condition of anonymity because they were not authorized to brief reporters.
