A stabbing rampage in a southern English town has been declared a "terrorist incident" by British police.
Three people were killed and three more wounded on Saturday evening (June 20) in Reading, around 40 miles west of London.
A 25-year-old man, named by a security source as Libyan national Khairi Saadallah, was arrested on suspicion of murder.
The UK's most senior counter-terrorism police officer, Neil Basu, said the attack was declared a terrorist incident on Sunday morning (June 21) after investigations through the night.
"From our inquiries undertaken so far, officers have found nothing to suggest that there was anyone else involved in this attack and presently we are not looking for anyone else in relation to the incident."
The attack took place in a park where a Black Lives Matter protest had been held a few hours earlier but Basu said the attack and the demonstration were not linked.
Prime Minister Boris Johnson said thoughts were "very much with the family and friends of the victims" and that changes would be made to British law if necessary.
"If there are lessons to be learned, if there are changes that need to be made to our legal system to stop such events happening again, we will not hesitate to take that action."
Opposition leader Keir Starmer said he wanted to talk to the prime minister to discuss a response and that this was not a time for "party politics".
