London, United Kingdom. The government of the United Kingdom, in consultation with anti-terrorist officers, have raised the threat level for additional terrorist attacks to its highest level in England, following the Manchester attack.

Britain has increased its security threat level to “critical” from “severe” following a suicide attack in Manchester that killed 22 people, including children, Prime Minister Theresa May said on Tuesday. The concern stems from the ISIS suicide bomber having had a support network and bomb builder, all of which remain at large as officials desperately search for them, before another attack can take place.

Prime Minister May meanwhile, has also said members of the armed forces would boost security at key sites and military personnel might be deployed at public events such as concerts and sports events to try and prevent fresh attacks nationwide, as a sense of panic builds amongst England’s citizens, knowing more trouble is coming, but not clear where.

May said the independent body which sets the threat level had recommended it be raised after a man named by police as Salman Abedi set off an improvised bomb on Monday night as crowds streamed out of a concert. The concerns based upon intelligence that more terrorist are loose inside the UK and actively working to carry out new attacks nationwide.

“It is now concluded on the basis of today’s investigations that the threat level should be increased for the time being from severe to critical,” she said in a televised statement following a meeting of the government’s crisis response committee.

“This means that their assessment is not only that an attack remains highly likely but that a further attack may be imminent.” Police ask that British citizens report any strange activity, especially that involving persons from middle eastern or Islamic backgrounds.
