Police confirmed a man behaving suspiciously had been killed in Subirats, 30k, from Barcelona, at around 5:05pm local time (5:05pm UK time).
Mossos d’Esquadra, the region’s police force, tweeted: “The suspect is wearing an explosive belt of attached to his body. The individual has been shot dead.”
The force had earlier said a police operation was in place after receiving reports of a suspicious person in the area.
But it did not confirm whether the man is Younes Abouyaaqoub, who officers believe was the driver in last week’s Barcelona terror attack.
A spokesman said: “We cannot at this stage confirm that the man who has been shot is Younes Abouyaaquoub.
“What we can confirm is that the suspicious person was wearing what appeared to be an explosives belt.
“I cannot say at this stage whether he has been killed or not.”
