Houthi-run al-Masirah TV announced Saturday that the Saudi-led alliance backing the Yemeni government conducted six raids vernight on Houthi sites in Yemen's central province of Marib.

The Friday night strike hit locations in the Jabal Murad and Joubah districts, without giving further information, the television said.

The alliance or the Yemeni government have not made any statements.

To keep them from creeping on the government stronghold, the opposition has occasionally attacked the Houthi militia.

The districts are situated a few miles east of the Houthi-held capital, Sanaa, in the extreme north and west of the government-held province.

Since late 2014, when the Iran-backed Houthis captured several northern provinces and pushed President Abd-Rabbu Mansour Hadi's internationally recognised government out of Sanaa, Yemen has been mired in civil war.
