Spanish police said on Monday they had shot a man armed with a knife as he tried to attack a police station in the northeastern region of Catalonia.
Regional Mossos police said on Twitter the man had entered the police station in Cornella, near Barcelona, just before 0400 GMT "with the aim of attacking the officers" adding he had then been shot.
A Mossos spokeswoman said she could not give any further information.
State broadcaster RTVE said the attacker was a 29-year-old Algerian resident in Cornella with Spanish identity documents, and had been killed by the gunshot.
Last Friday, Barcelona commemorated the first anniversary of an Islamist assault in which a young man drove a van down a busy central boulevard, killing 14 and injuring over 100 in Spain's worst attack in more than a decade.
