Story highlights Local hospitals have been overwhelmed with victims, officials say

Houthi rebels are fighting pro-government forces backed by a Saudi-led coalition

Sanaa, Yemen (CNN) Airstrikes hit a wedding celebration in a rebel-held portion of Yemen, killing at least 30 people, local officials said, amid a months-long conflict in which a Saudi-led coalition has bombed rebel areas.
