The Saudi-led coalition fighting the Houthi Rebel forces in Yemen have begun a 5-day ceasefire.
Saudi officials say this will allow deliveries of relief supplies into the country.
UN envoy Ismail Cheikh Ahmed says they're hoping the truce will be extended.
"We have two points regarding the humanitarian truce: first, it has to be unconditional and second, humanitarian aid should be able to reach all Yemenis in the south, the north, the east, and the west."
UN official Rupert Colville says the campaign in Yemen over the past month has been devastating to the locals.
"The six days from the 4th to the 10th of May, that is to yesterday, have been the deadliest since fighting began in Yemen on the 26th of March. The total of at least 182 civilians reported killed during that period, almost exactly half of them women and children -- that's 51 children and 41 women."
Saudi-led forces began bombing Houthi targets in Yemen at the end of March.
Around 15-hundred people have been killed since the campaign began.
