Fallout after UK terrorist killing

British police were searching two homes yesterday after shooting dead an extremist who knifed two people in London in an attack claimed by the Islamic State group.

That came as the government vowed a review of the system for the early release of convicted terrorists.

Sudesh Amman, 20, who was wearing a fake suicide vest, was shot on a busy shopping street in south London on Sunday.

He was described by an Islamic State propaganda arms as "an IS fighter" who "carried out the attack in response to a call to target nationals" of countries belonging to the global coalition fighting it.

Amman was recently freed early from prison. He was arrested in London in May 2018 on suspicion of planning a terrorist attack and imprisoned for 40 months in December of that year for 13 separate offenses.

Yesterday saw counter-terror officers conducting searches at addresses in south London and Bishop's Stortford, north of the capital.

Police said they had been on a "proactive counter-terrorism surveillance operation" on Sunday with armed officers following Amman on foot following his release. The attack in the Streatham district came just over two months after a similar incident when police shot dead a convicted terrorist on early release near London Bridge.

He had stabbed two people to death after attending a prisoner rehabilitation conference.

Prime Minister Boris Johnson yesterday unveiled plans to change the system on handling releases of convicted terrorists.

But London mayor Sadiq Khan told ITV television he was "angry" that the government had not already acted to change the law.

He claimed there were more than 70 people in London who have been convicted of terrorist offenses, served time in prison and been released.

Amman had been staying in a hostel for newly-released prisoners, according to media.

He stole a knife from a store and attacked a woman then a man on the same street before being shot.

The man, in his 40s, was in a non-life-threatening condition, police said, while the woman, in her 50s, was discharged from hospital.
