LONDON (Reuters) - British Prime Minister Boris Johnson called the stabbing in central London that killed two people a "terrorist" attack.
Before his early parliamentary election on June 12, Johnson promised to work to prevent premature and spontaneous convictions for serious crimes out of jail, Reuters reported.
British police said earlier that the bomber had already been released from prison after being convicted of terrorism.
Britain's opposition Labor Party criticized Johnson's government record in fighting crime and terrorism.
Opposition London mayor Sadiq Khan also said "there are urgent questions that need to be answered with regard to dealing with serious criminal convicts."
Two people were killed yesterday in a knife attack by a man at the London Bridge in central London while police killed the bomber.
