One man arrested over Barcelona attack: regional police

A man was arrested over an attack in Spain's popular seaside city of Barcelona that saw a van plough through a street packed with pedestrians, killing at least one person and injuring over 30 others, police said today.

"We arrested a man and we are treating this as a terrorist attack," police in the Spanish region of Catalonia, where Barcelona is located, tweeted. They added that no one was holed up in any bar of central Barcelona, denying what a police source had earlier said.
