As part of the international day of protest, marches, demonstrations and vigils were organised across the world for the 15th July 2006. Several different protests were organised across the United States, with protests and vigils in the Middle East, London and Australia.
In London after a short march from Marble Arch to the American Embassy in Grosvenor Square, the crowd was addressed by numerous speakers including Victoria Brittain, co-author with Moazzam Begg of "Enemy Combatant", Yvonne Ridley, Ghada Razuk of the Stop the War Coalition,Azzam Tamimi and others. In total, speeches outside the embassy lasted for over an hour and a half.

Omar Deghayes from Brighton is one of the British residents known to be imprisoned in Guantanamo. His sister, Amani, speaking with a perfect Home counties accent and wearing a T shirt with the web address http://www.save-omar.org.uk/ , told how when she was 8 years old, their mother had fled with five children from Libya to Britain.

Shortly after her speech it was announced that she and Jackie were going to take a petition to the embassy and a policewoman stepped forward to open the fence between the crowd and the embassy. This petition was for an independent inquiry into the deaths of prisoners at Guantanamo and for its closure.

George Galloway spoke, amongst other things, of the case of Babar Ahmad. He said that he had become a friend of Ahmad's family and that he totally believed in his innocence. The final speaker was barrister Hugo Charlton from CAMPACC.

The organisers then announced that they would be proceeding to the Home Office via Marble Arch. Here a petition was to be handed in demanding that Britain ensures the safe return to Britain of the British residents still in Guantanamo. I didn't see how many (if any) dispersed from Grosvenor Square, but I counted about 215 people still with the march.
