Tony Blair has issued a statement at a press conference with the leaders of the G8 nations lined up behind him, Mr Blair said: "We condemn utterly these barbaric attacks. All of our countries have suffered from terrorism... we are united in our resolve to confront and defeat this terrorism that is not an attack on one nation but on all nations and on civilised society everywhere," he said.

Tony Blair said the G8 leaders would continue their discussions and would not allow terrorists to halt a summit aimed at helping the world's poorest people.

The Independent reports: Many people are feared dead after four terrorist blasts across central London, hitting trains and a bus. All public transport is halted and Londoners have been told "Stay where you are".

In New Zealand, Prime Minister Helen Clark told TVNZ's One News: "I have asked them to convey the deep shock and sympathy and concern of the Government and people of New Zealand to the office of Tony Blair."

The New Zealand High Commission in London has set a communications room where "they are there to take calls from New Zealanders in London who might want to know if any one has been reported as missing," Helen Clark said.

There are approximately 250,000 New Zealand passport holders in the United Kingdom. It is unknown whether any New Zealanders are among the casualties in the bomb attacks.

The Guardian reports: Accounts from people who witnessed the explosions in central London today - "I was on the bus in front and heard an incredible bang, I turned round and half the double-decker bus was in the air ... It was a massive explosion and there were papers and half a bus flying through the air, I think it was the number 205. There must be a lot of people dead as all the buses were packed, they had been turning people away from the tube stops. We were about 20 metres away, that was all," Belinda Seabrook, who was on a bus travelling from Euston to Russell Square, London.

"People were running this way, panicked. They knew it was a bomb. Debris flying all over, mostly glass," Jay Kumar, owner of a newsagent near the bus blast in Russell Square.
