B-2 bombers used against Houthis, but impact limited - CNN

B-2 bombers have been deployed in US strikes against Iran-backed Houthi militants in Yemen, but the campaign has seen limited success, CNN reports citing three sources with knowledge of the campaign.

The operation has cost nearly $1 billion in less than three weeks, according to the report, but does not appear to have significantly degraded Houthi capabilities.

One source told CNN the Pentagon may request supplemental funding.
