LONDON, United Kingdom: A series of deadly blasts that rocked London subway and a packed double-decker bus have drawn shock, anger and sympathy from around the Muslim, Arab and Western world.

Meanwhile, a massive intelligence investigation is under way to find those responsible for the bomb attacks in the heart of British capital which killed at least 40 and left 700 injured and is the worst attack on London since World War II.

British Muslim groups including the Islamic Human Rights Commission have also condemned the blasts and appealed for calm amid fears of an anti-Muslim backlash.
UK Prime Minister Tony Blair said the terrorists "acted in the name of Islam," but said he knew most Muslims worldwide "deplore this act of terrorism".

He welcomed a statement by the Muslim Council of Britain, which said it "utterly condemns the perpetrators of what appears to be a series of coordinated attacks."

"These evil deeds make victims of us all," the council said in a statement. "The evil people who planned and carried out these series of explosions in London want to demoralize us as a nation and divide us as a people … All of us must unite in helping the police to capture these murderers."

The Council called for prayers for the victims at the country's 800 mosques and urged full cooperation with police.

The Group of Eight most industrialized nations declared at their summit in Gleneagles, Scotland "We condemn utterly these barbaric attacks."

"We are united in our resolve to confront and defeat this terrorism. This is not an attack on one nation, but on all nations and on civilized people everywhere," Blair said, flanked by the leaders of G8 nations Canada, France, Germany, Italy, Japan, Russia and the United States as well as those of guest countries China, India, Brazil, Mexico and South Africa.
