London came to a standstill at noon today as the capital paid its respects to the victims of the Asian tsunami disaster.

A three minute silence was called at 12 pm GMT when millions of people fell still.

Flags on government buildings and Buckingham Palace flew at half mast.

However, the call for a three minute silence has been criticized. Some questioned whether the length of the tribute, which is a minute longer than that observed for fallen soldiers in November's remembrance day services , was appropriate.

It is thought that around 150,000 people, including 200 Britons, died following the Boxing Day disaster.

A massive earthquake shook the seas in south east Asia sending a devastating wave crashing through the coastlines of many countries.

Londoners, along with the rest of the UK, have been unequivocal in their response to an appeal for funds to help restore order to stricken areas.

More than £76million has been donated so far and earlier today the Government promised to increase its contribution.

Speaking on the BBC's Radio 4 Prime Minister Tony Blair forecast Government spending would "more than match" the generosity of the British people.
