Young Australian boy missing after van attack in Barcelona

BARCELONA -- Australian Prime Minister Malcolm Turnbull has asked people to pray for a young Australian boy who is missing after a vehicle attack on a popular Barcelona promenade that killed 13 people.

Turnbull said Saturday that the boy's mother was badly injured and is in a hospital following Friday's attack at the Las Ramblas promenade. Turnbull says the boy's family is searching for him. He did not release the boy's name.

Turnbull says: "All of us as parents know the anguish his father is going through, and his whole family is going through, as they rush to seek to find him in Barcelona."

Australian Foreign Minister Julie Bishop says four Australians were injured in the attack.
