British Prime Minister Theresa May has responded to the explosion at the Manchester Arena late Monday night, saying the government is "working to establish the full details of what is being treated by the police as an appalling terrorist attack."

May added that "all our thoughts are with the victims and the families of those who have been affected." Labour Party leader Jeremy Corbyn called the incident "terrible," and said his thoughts are with "all those affected and our brilliant emergency services," while Liberal Democrat leader Tim Farron sent his "deepest condolences to the victims and families in Manchester. As always, our emergency services have shown great bravery and strength." The Guardian reports that in the wake of the explosion, which left at least 19 people dead and 50 injured, campaigning for June's general election has been suspended.
