A Lot Happened There Around Russell Square and Had Reverberations Everywhere?

New Thinking Allowed: Russell Square: A Crucible of Consciousness with James Tunney

According to Wikipedia -

On 7 July 2005, two terrorist bombings occurred near the square.

One of them was on a London Underground train at that moment running between King's Cross St Pancras tube station and

Russell Square tube station, and another was on a bus on Tavistock Square, near Russell Square.

To commemorate the victims, many flowers were laid at a spot on Russell Square just south of the café.

The location is now marked by a memorial plaque and a young oak tree.
The square was also the site of a mass stabbing in 2016.
