The European Union on Monday approved sanctions on son of the former president, Ahemd, and leader of the Houthi militant group, Abdulmalik Al-Houthi, agencies reported.
The two guys have been blamed for expansion of the Houthi militants in all Yemeni cities and threatening the transition process primarily through blowing the Gulf Initiative for transition.
The reports quoted a statement by the EU as saying the sanctions came within the EU response to the UN Security Council's resolution No.2216 on Yemen.
The resolution, passed early this year after the Houthi militants with support from the forces loyal to the former present Saleh had ousted the transition government, extended last year's sanctions on Saleh and Houthi military leaders for attempts to undermine the transition process.
The sanctions included freezing assets and travel bans.
The resolution was passed under the seventh chapter of the UN charter and called on the Houthis to cede power, withdraw from cities, return state weapons and stop violence and threats to regional countries.
The EU condemned the violence by the Houthi militants and pro-Saleh forces while affirming the crisis in Yemen should be resolved with political solutions, the reports added.
Meanwhile, the battles between pro-government and pro-Houthi forces continued in several cities.
In Jawf, the popular resistance ambushed Houthis killing more than a dozen as fierce battles were continuing since early Monday, locals said.
In Aden, the popular resistance repelled an attack by the Houthis who have been trying to regain control of areas.
There were also casualties from both sides in battles in the cities of Taiz, Dhali and Lahj.
