LONDON, June 21 — British police today said that a stabbing attack in a southern English town that left three people dead and another three injured was being treated as a terrorist attack but that there was no intelligence on any further attacks.

“This was an atrocity,” Britain’s top counter-terrorism officer, Neil Basu, said, adding that unarmed police officers had tackled the attacker.

Basu said that counter-terrorism police are now leading the investigation and that the attack is not linked to the Black Lives Matter protest in the same park in Reading a few hours before yesterday’s attack. — Reuters
