A power plant in the Yemeni city of Maarib which supplies power to the capital Sanaa and many of the surrounding provinces, has been shut down after it was attacked by tribesmen.

Shia Houthis and the Sunni tribesmen have been rallying fighters for confrontation in the oil- and gas-rich province of Maarib - a sign of an increasing sectarian divide in the Arabian Peninsula nation.
