Security officials say Yemen's Shiite rebels have captured a town south of the capital Sanaa, where they have also blown up the house of a rival Islamist politician.

They say the rebels, known as the Houthis, have also stormed the headquarters of Sanaa's local government on Sunday_chasing out the capital's governor, who they accuse of corruption.

The Yemeni officials spoke on condition of anonymity because they were not authorized to speak to the media.

Sunday's developments reflected the growing strength of the Houthis, who overran Sanaa last month and captured a Red Sea port last week along with a province south of the capital.

Early on Sunday, the Houthis captured the town of Yarim about 170 kilometers (106 miles) south of Sanaa.
