The U.N. says Secretary-General Ban Ki-moon is disappointed that the humanitarian pause he called for in Yemen did not take hold but has not lost hope that a suspension in the fighting will take place.

U.N. spokesman Stephane Dujarric said Monday that despite continued fighting and airstrikes, humanitarian workers were able to distribute some desperately needed aid.

Dujarric says the U.N. stands by the commitments it received for the pause, which was to start at midnight Friday local time.

He says discussions are still taking place with the parties.

Dujarric also says Ban retains confidence in the U.N. mediator, Ismail Ould Cheikh Ahmed.
