As many as 23 Houthi militants and Saleh's supporters were killed in an artillery shelling by the Arab coalition forces on their posts in Hajjah governorate, said the Yemeni Media Center of the Fifth Military Region on Sunday. 

The center said the coalition aircraft targeted on Saturday gatherings of the militias and destroyed two caches of weapons and ammunition in the relevant area.

Blasts lasted long following the demolition of the two stores, according to pro-army sources.
