Can't believe I'm only hearing of this so many hours after and on here, too busy posting on the City and only just come to off topic.
Awful how this is such a normalised event these days that nobody at work has even spoken about it yet (I assume they're unaware too).
RIP to the victims, hope it is isolated as seen other places now in lockdown.
* One more thing, sorry probably not appropriate for this, but whenever I read or hear the words Yom Kippur, I always get a mental image of Neil Diamond in the Jazz Singer.
