Yemeni warplanes on Wednesday hit a makeshift camp for civilians fleeing fighting between the government and Shi'ite rebels, killing dozens of people, witnesses said.
An ambulance driver counted 120 people ferried to the local hospital, among them dozens of dead. Three other witnesses reported a similar number of casualties in the area near the rebel-controlled town of Horf Sufyan, north of the capital.
The driver spoke on condition of anonymity because out of fear of government retribution.
Government officials denied the strikes had taken place, but a civil servant in the local government confirmed the attack.
