Political tensions between Algeria and Spain soured further this week after Algiers suspended a “friendship” treaty between the nations, three months after Madrid endorsed Morocco’s autonomy plan for the Western Sahara.

Spain’s Foreign Minister Jose Manuel Albares said gas flows from Algeria to Spain were unaffected by the decision, adding that Madrid would respond ‘firmly” to the move, while the European Commission called Algiers’ decision “extremely worrying”.

In March, Madrid recognised Morocco as the de facto power in Western Sahara in an effort to improve relations with Rabat.
