Ansarullah has already recruited over 5,000 young Yemenis in Sa'ada, Amran and Hajjah provinces to fight the Saudi aggressors, the Yemeni sources said.

The sources reiterated that several military bases have been considered for training the volunteer forces in the Eastern parts of Amran province.

On Tuesday, another source said that the Yemeni army and Ansarullah popular forces have lined up behind the borders with Saudi Arabia in preparation for a possible ground battle against the Saudi regime's aggressive army.

An informed source close to Ansarullah announced that a large number of revolutionary forces and the Yemeni army's infantry units and presidential guards have deployed behind the borders with Saudi Arabia, the Arabic-language Yemen Press reported.

The source declined to further comment on the development, but the line up has caused increasing speculations about imminent heavy clashes along the Yemen-Saudi Arabia borderline.
