Protesters shout slogans in favour of Western Sahara independence campaigner Aminatou Haidar, in front of Spain's Foreign Affairs building in Madrid, December 10, 2009. A tussle between Morocco and Spain over activist Aminatou Haidar, who is staging a hunger strike, has become the biggest test yet of a diplomatic honeymoon which has boosted cooperation on security, illegal migration and trade. Haidar has consumed only sugared water for 25 days after Moroccan authorities turned her away from the Western Sahara following a trip abroad, and put her on a plane to Lanzarote in Spain's Canary Islands.
