A police officer has died and another has been injured after a backpack exploded in the northern Spanish city of Oviedo.

The explosion happened when officers from Spain's canine unit and explosives disposal unit arrived and examined a suspicious backpack following reports of a dispute between neighbours on Tuesday morning.

A woman was shot during the dispute and the suspect is still at large, police said.

Both she and the injured officer have been taken to hospital for treatment.

Spanish police paid tribute to the officer, who has been named as Juan José, in a statement on X and said: "Our hearts are with his family, friends, colleagues and loved ones."

Responding to the incident, Spanish opposition leader and President of the People's Party Alberto Núñez Feijóo said: "What happened in Oviedo is heartbreaking.

"My condolences to the family of the officer who died and my best wishes for the recovery of the one who was seriously injured."
