Initial reports are still very sketchy, although Tom Winter of NBC News tweets, “Law enforcement officials say at least 20 dead and hundreds have been injured following reports of an explosion in Manchester, UK.”
UPDATE (8:20 PM EDT): Manchester police are currently reporting 19 dead, approximately 50 injured, and add, “This is currently being treated as a terrorist incident until police know otherwise.”
“UK authorities suspect a possible suicide bomber responsible,” Winter tweets.
UPDATE (8:31 PM EDT): “How many casualties were caused by the explosion and how many by the ensuing stampede?”, Allahpundit asks at Hot Air. “Ed [Morrissey] emails to say he’s seen reports saying that some people were trampled.”
“Twitter has a running Trends item for further information. An awful lot of the tweets are people looking for missing friends,” Charlie Martin writes at PJM.
