Prime Minister Theresa May said the UK “stands with Spain against terror” following the deadly attack in Barcelona.

Mrs May condemned the “terrible” assault in the Spanish city which saw a van plough into pedestrians and follows a spate of similar attacks in London in recent months.

She said: “My thoughts are with the victims of today’s terrible attack in Barcelona and the emergency services responding to this ongoing incident.

“The UK stands with Spain against terror.”

Meanwhile, US president Donald Trump wrote on Twitter: “The United States condemns the terror attack in Barcelona, Spain, and will do whatever is necessary to help. Be tough & strong, we love you!”
