May: UK stands shoulder-to-shoulder with Spain

The UK stands "shoulder-to-shoulder with Spain" after Thursday's attacks, Prime Minister Theresa May has said.

Mrs May said the UK government believes that a number of British nationals were caught up in the attack and that officials are urgently investigating reports of a child, believed missing, who is a British dual national.

She said countries must "work together if we are to confront this evil of terrorism" and the "perverted, extremist ideology which drives it".
