UPDATE 1-Britain to toughen rules for terror convicts after London attack

British Prime Minister Boris Johnson will set out tougher rules on releasing people convicted of terrorism offenses after an Islamist attacker injured two people in a stabbing spree days after he was set free halfway through his prison term. Sudesh Amman, who was jailed in 2018 for possession of terrorist documents and disseminating terrorist publications, was shot dead by police on Sunday after he went on the rampage with a stolen 10-inch (25 cm) knife on a busy London street.

Amman had previously praised the Islamic State militant group, shared an online al-Qaeda magazine and encouraged his girlfriend to behead her parents. Johnson said the government would announce fundamental changes to the system for dealing with those convicted of terrorism offenses.

"Those measures will build upon the actions we have already put in place," said his interior minister, Priti Patel. She said there would be legislation to end the early release from prison of counter-terrorism offenders. "It is right that these individuals are kept behind bars," Patel said.

British politicians have repeatedly discussed tougher rules on terrorism, calls that increased after a former convict killed two people and wounded three more before police shot him dead near London Bridge in November. Johnson said that since that attack, the government had "moved quickly to introduce a package of measures to strengthen every element of our response to terrorism – including longer prison sentences and more money for the police".

SUNDAY IN STREATHAM Sunday's attacker, Amman, had recently been released from prison, according to police, having been jailed for promoting violent Islamist material.

He went on the rampage at around 1400 GMT on Streatham High Road and had strapped a fake bomb to his body. He stabbed two people, seriously injuring a man in his 40s, while a third suffered minor injuries caused by shattered glass when police opened fire. Amman was under surveillance at the time of the attack by armed police, who shot him dead.

In November 2018 he pleaded guilty to possession of terrorist documents and disseminating terrorist publications, and the following month he was sentenced to more than three years in prison. He was 17 and living at home with his mother and younger siblings when he first began committing terrorism offenses, according to authorities. Police became aware of his activities in April 2018 and he was arrested by armed officers in a north London street a month later.

When officers examined his computers and phone, they found he had downloaded material about making explosives and carrying out terrorist attacks, according to prosecutors. Messages showed that he had discussed with his family, friends, and girlfriend his extreme views and desire to carry out an attack, often focused on using a knife, prosecutors said.

In December 2017 Amman posted a picture of Islamic State leader Abu Bakr al-Baghdadi, who was killed in a U.S. raid in Syria in October, and told his brother in a message that "the Islamic State is here to stay". He also described Yazidi women as slaves and said the Koran made it permissible to rape them, and in another message, he encouraged his girlfriend to behead her parents.

Police said he had shared an online al-Qaeda magazine with his family and while in a discussion about school with a sibling he wrote he would "rather blow me up".
