Japan Prime Minister Fumio Kishida says the shooting was a 'barbaric' and 'unforgiveable' act.

Local media say Shinzo Abe appears to be in cardiorespiratory arrest, a term often used in Japan before a feared death can be officially confirmed by a coroner.

Robert Crimo has been charged with seven counts of first-degree murder and is being held without bail until a preliminary hearing on July 28.

The man charged with killing seven people at a Chicago-area July Fourth parade slipped past the safeguards of an Illinois 'red flag' law designed to prevent people deemed to have violent tendencies from getting guns, officials say.
