You can see part of what happened there (Hebrew) in my Peertube mirror of our local group's Youtube channel: https://tube.shela.nu/w/hvkibKEvhr3idzNsg6f7im .
This has been but one of many local events in many places all over the country. Our government has failed to prevent that horrible day. Furthermore, at that day and the following months, the government simply did not exist: We the people had to do its job. And so far almost none of them has resigned.
Today is 7.10. Elections are on 27.10. In 20 days. And it is our job now, as the people to replace the failed government.
BTW: The government tried to shift even the memory: the official day of remembrance as set by the government was, according to the Jewish Calendar, two days ago. It is set to two days after the date on the Jewish calendar, as the date is a holiday, and you don't want to mix the two.
But the families of the victims have created their own ceremony. And managed to label it as the "National Ceremony". It has gained more attention than the official one. Broadcasted on major TV channels (not on the BB-TV channel-14, of course. But that one is an anti-press channel).
That ceremony will be held later this evening. The protests today were arranged by "the protesters" (loosely aligned with #TheDemocrats [edit: accidentally tagged 'Democrats'. I meant the Israeli left-wing party]). The ceremony is of a movement called Kumu that is more of a centric movement that aims to unite everyone.
