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
