Authorities have been criticised for their response to the disaster. On Sunday angry protesters threw mud at Sanchez, King Felipe and Queen Letizia shouting 'murderers' and 'get out'.Sanchez met with EU Commission President Ursula von der Leyen on Wednesday, who said the bloc had activated the Copernicus satellite system, an earth monitoring programme, to help coordinate rescue efforts and pledged that the EU will help Spain.
