I attended a protest for Palestine on the 15th May. The day before, there was a protest in London that had been planned on the anniversary of the Nakba of 1948. I didn’t go to London but some footage can be seen here.
The protest also took place after the killing of Palestinian journalist Shireen Abu Akleh.
It was a pretty small protest. It was due to start at 2pm, but at this time there was hardly anyone there.

More people began to trickle in after 2pm, so the crowd became closer to 150 people.

Initially the protest was in the square proper, but it was moved to make it more visible to passers by.
There was both chants being led and some speeches. Some children (I’m guessing under the age of 10) also led chants, which I didn’t film as I don’t want to put that online (I try to avoid filming children if possible).
