A proposed U.N. resolution would demand that all parties in Yemen immediately honor an April cease-fire and resume peace negotiations on the basis of a roadmap covering political and security issues.

The draft Security Council resolution, obtained Wednesday by The Associated Press, also calls for transparent and timely investigations of alleged violations of international humanitarian and human rights law — and accountability for those responsible for violations and abuses.

Britain's U.N. Ambassador Matthew Rycroft said Tuesday he expects to circulate the draft to the council "in the coming days." It was first published by Inner City Press.

The U.N. special envoy to Yemen, Ismail Ould Cheikh Ahmed, drafted the roadmap. It was immediately rejected by President Abed-Rabbo Mansour Hadi of Yemen's internationally recognized government.
