LONDON (Reuters) - A man has admitted killing three people during a stabbing spree in the southern English town of Reading in June, the BBC reported on Wednesday, an attack police declared a terrorism incident. Khairi Saadallah, 26, was accused of murdering the men and stabbing three others with a five-inch knife during the attack in a park in the town on the evening of June 20. The BBC said Saadallah, who a security source told Reuters at the time of the incident was a Libyan national, had admitted murder and attempted murder at a hearing at London’s Old Bailey Central Criminal Court.However, while the prosecution said the attack was a pre-meditated terrorism attack, his defence team did not accept that and said his mental health needed to be taken into account, the BBC reported. Saadallah had targeted a group of seven friends, stabbing three fatally - James Furlong, 36, and David Wails, 49, from Britain and U.S. national Joseph Ritchie-Bennett, 39. Another of the group required 28 stitches to a head wound. Two other men who were sitting with friends nearby were also stabbed, one in the back while the other suffered a cut to his cheek.
