Spain's northeastern region of Catalonia, hit last week by two Islamist militant attacks that killed 15 people, will deploy more police, install bollards in Barcelona and step up security around stations and tourist landmarks.
The aim is to strike a balance between security and not overloading residents with restrictions.
"We're looking at introducing (street) obstacles that could be mobile," Joaquin Forn, who is in charge of home affairs in Catalonia, told a news conference on Wednesday.
