A U.N. official says airstrikes launched by the Saudi-led coalition on a water well in northern Yemen have reportedly killed 30 people.

The U.N. Humanitarian Coordinator for Yemen, Jamie McGoldrick, said in a statement on Monday that the casualties in the village of Beit Saadan included first responders and children.

McGoldrick says he is "deeply disturbed by the unrelenting attacks on civilians and on civilian infrastructure," and urges rival parties to resume a cease-fire declared by the U.N. in April.

Yemen's conflict pits the internationally recognized government, which is allied with a Saudi-led military coalition, against Shiite Houthi rebels and forces loyal to a former president.

The Saudi-led coalition has been carrying out airstrikes against the Houthis and their allies since March 2015.
