Turnbull condemns Spain terror attack

Australia stands in absolute solidarity with the people of Spain in the fight against Islamist terrorism, Prime Minister Malcolm Turnbull says.

Responding to a deadly attack in Barcelona that has claimed at least 13 lives - the federal government puts the toll at 16 - Mr Turnbull said the love and prayers of Australians were with the victims and their families.

"This is a global battle against terrorism," Mr Turnbull told reporters in Canberra on Friday.

Australia's national terrorism threat level remains at probable following an assessment by security and intelligence authorities.

"We've had a look at it under the lens of the tragic events in Spain last night and at this stage, there is no change," Director-General of Security Duncan Lewis said.
