The announcement came hours after Iranian-backed Houthis reportedly cut a vital supply route to besieged city of Taiz

Yemen’s Saudi-backed government has announced the start of a new military operation to retake all territory held by the Houthis, even as the militant group made fresh gains on the ground, reportedly encircling a government-held city.

Rashad al-Alimi, the head of Yemen’s presidential council, said in a statement on Sunday: “I announce today the start of military operations to retake the remaining territories of the republic and extend the authority of the state and its institutions across the entire national territory.”
