The devastating attack on the Ariana Grande concert in Manchester last night left the world stunned, but it looks like the worst is still yet to come. ISIS claimed responsibility for the attack which claimed the lives of 22 concertgoers while injuring close to sixty others although their involvement has yet to be confirmed by intelligence agencies. Authorities have discovered no evidence of a link between the attacker and an established terror group, a British counterterrorism official told CNN.
British Prime Minister Theresa May has since raised the MI5 threat level of international terrorism to the highest possible level of ‘critical’ in Great Britain following the decision of the government’s independent crisis response committee.
The new terror level also comes following the news Manchester police had raided two other sites in the city resulting in setting off a controlled explosion in the one, and the arrest of a 23-year-old man in a third location. The perpetrator of the yesterday’s concert attacks has since been identified as Manchester resident Salman Abedi, 22, who died in the act of terror. 
Police have since raided the homes of Mr. Abedi as well as the nearby home of his brother Ismail. No other details on the perpetrator have been released as of yet.
The government’s decision to raise the threat level to critical means that “an attack is expected imminently,” per the MI5 website. The last time the UK government raised the threat level to ‘critical’ was June 30th, 2007 following a series of attacks in both London and Glasgow which claimed the life of one at Glasgow International Airport.
A threat level of ‘critical’ allows the government to deploy armed soldiers, as opposed to regular police, at large public events such as sporting events or concerts.
