I saw this news Saturday morning (Beijing time) on Chinese media. The incident happened Friday. The number I give in the title above does not include the killer, who died running from the police.
“A man reportedly tried to stop the attacker but was struck with a blunt object and later died in hospital.”
Wow — if confirmed, rather like the Bondi Beach hero (who survived). In Taipei, the attacker did go on to attack others after this attempt (as occurred with the Bondi incident, too, though it’s likely lives were saved in that case).
