Aminatou Haider, a Western Saharan activist, has been staging a hunger strike in Spain's Lanzarote airport for almost one month.

Moroccan authoraties expelled her from her native Western Sahara for refusing to say she was Moroccan.

The independence campaigner says she will keep refusing food until she is allowed back to her homeland.
