UNITED NATIONS — The U.N. Security Council is calling on Secretary-General Ban Ki-moon to convene peace talks on Yemen.

A council statement Tuesday night also welcomed the start of a five-day pause in the fighting to allow the delivery of humanitarian aid, but it warned that "all parties will need to transparently and reliably suspend military operations."

The statement says U.N.-guided talks should include all parties and must be a Yemeni-led process. The U.N.'s new Yemen envoy Ismail Ould Cheikh Ahmed began his first visit to the country on Tuesday.

Officials have said there is no set time or place yet for U.N.-led talks on Yemen. The council statement welcomes a separate May 17 conference in Riyadh in support of talks.
