I know that:
- 4 activists held a Palestinian flag on the balcony of the National Gallery overlooking the march. Samba joined them below on the pavement and were subsequently attacked by salute israel attendees.
-An activist scaled one of the large screens and disabled it.
-The fountains in Trafalgar square were (half) dyed red to represent the blood of the thousands of Palestinians killed during the 60 years of occupation
- Some people joined the march with a megaphone, attempted to chant and were pounced upon. Two others walked around the square covered in red paint and were arrested.
Thus far I think that there were at least 6 arrests made - they are all being held at Charing Cross station.
