Ismail Ould Cheikh Ahmed said on Twitter the talks would resume today. He says all sides in the conflict agreed to form a committee to look into what happened in the governorate of Amran, which reportedly came under attack by Yemen's Shiite rebels.
That attack halted the talks in Kuwait City.
Yemen's internationally recognized government, backed by a Saudi-led military coalition, is fighting the rebels known as Houthis who seized the capital, Sanaa, in September 2014. The Saudi-led forces entered the conflict in March 2015.
