UK Home Secretary on Manchester Arena explosion: 'This was a barbaric attack'

UK Home Secretary Amber Rudd on Tuesday (23 May) called the explosion at Manchester Arena in northern England that killed 19 people as a 'barbaric attack'. She called on the Mancunians to remain 'alert but not alarmed'. The attack appears to be the most deadly attack Britain has witnessed in a decade. British Prime Minister Theresa May, who called the incident 'an appalling terrorist attack', is set to chair a Cobra emergency meeting on Tuesday as she suspended her campaign activities.
