The failure of Riyadh's efforts for European action against Yemen.
Saudi Arabia is trying to convince the European Union to include Yemen's Ansarullah movement in the list of "terrorist" organizations. However, the concern of European countries about weakening the possible peace process in Yemen hindered the progress of these efforts.
According to this report, this campaign is part of Riyadh's broader effort to increase international pressure on Ansarullah.
This is while the Yemeni army has carried out almost daily retaliatory attacks against Saudi Arabia in recent weeks and after the resumption of the war that began more than a decade ago.
