Security officials say airstrikes from a Saudi-led coalition targeting Yemen's Shiite rebels have killed eight rebel fighters in a renewed attempt to cut their supply lines to the country's third largest city.

The officials, who remain neutral in the conflict that has splintered Yemen's armed forces, said Tuesday's strikes hit the Red Sea port city of Hodeida, which lies on a major rebel supply line to the heavily contested city of Taiz.

Yemen's fighting pits the Shiite rebels known as Houthis against the coalition-backed internationally recognized government.

Taiz is in government hands, but is besieged by the rebels. Securing Taiz would allow pro-government forces to push north toward the rebel-held capital, Sanaa.
