Former University of Cambridge students Jones, 23, and Merritt, 25, were fatally stabbed by the 28-year-old attacker at an event run by the Cambridge-based prisoner rehabilitation program Learning Together.
A kitchen porter named Mohammed who was on his lunch break on Friday near London Bridge has been revealed, was one of the fearless heroes who pinned down London Bridge terror suspects Usman Khan to the ground, after two people were stabbed in the attack on Friday.
Britain's Boris Johnson said Sunday he had ordered the security services to step up monitoring of convicted terrorists released early from prison, prompting accusations that he was exploiting the London Bridge attack for political gain less than two weeks before elections. "Our thoughts and prayers are with the families of Jack Merritt and Saskia Jones, and all those injured or affected by the attack on Friday".
London Bridge reopened to cars and pedestrians Monday, three days after a man previously convicted of terrorism offences stabbed two people to death and injured three others before being shot dead by police.
"There are enormous questions to be learnt from this bad event that happened last week and that is, what happened in the prison with this particular individual, what assessment was made of his psychological condition before he was released and also what supervision and monitoring he was under after coming out?" said opposition Labour Party leader Jeremy Corbyn.
"Jack lived his principles; he believed in redemption and rehabilitation, not revenge, and he always took the side of the underdog".
Meanwhile, two victims remain in hospital after sustaining injuries in the attack as another returned home. He's insisted that his son would not "wish his death to be used as the pretext for more draconian sentences or for detaining people unnecessarily".
Khan was wearing what appeared to be an explosive vest that was later determined to be fake, and bystanders armed with a fire extinguisher and a narwhal tusk pulled from the wall of Fishmongers' Hall helped to subdue him.
The father of one of the London terror attack victims is slamming media reports attempting to use his son's death as "vile propaganda".
He was then conditionally released from jail around a year ago under so-called licensing conditions after serving about half of his jail term.
"It's not lenient policies that are to blame, it's the destruction of the probation service that is supposed to monitor and supervise prisoners after release, & rehabilitation services", he said on Twitter.
Merritt's family also cautioned against knee-jerk responses.
That is also the view of the main opposition Labour Party, which noted that the Conservatives have been in power for almost a decade but had chosen not to tighten the laws around terrorism sentencing.
