World leaders Thursday strongly condemned the blasts earlier in central London which left at least two people dead and more than 185 injured.

A number of people were killed in explosions on London's transport system at rush hour on Thursday morning, causing chaos in the British capital. British Home Secretary (Interior Minister)Charles Clarke confirmed that the explosions were terrorist attacks, adding that "four explosions have been confirmed."

In a statement, British Prime Minister Tony Blair said, "Perpetrators of today's attacks will not succeed."

"The bombing will not in any way limit our resolve to uphold themostly eagerly held principles of our societies and to defeat those who impose that fanaticism and extremism on all of us," Blair said, adding "We shall prevail."

US President George W. Bush vowed Thursday the war on terrorismwould continue following deadly blasts in London until "an ideology of hate" had been overcome.

"They have such evil in their heart that they will take the lives of innocent folks. The war on terrorism is on," Bush told reporters on the sidelines of the summit of Group of Eight leadersin Gleneagles, Scotland.

"I was most impressed with the resolve of all the leaders in the room. Their resolve is as strong as my resolve," Bush said.

"We will find them and bring them to justice. And at the same time we will spread an ideology of hope and compassion that will overwhelm their ideology of hate," Bush said.

The secretary general of the North Atlantic Treaty Organization (NATO) condemned the "appalling attacks," calling for "the international community and members of the Alliance to remain united in the fight against terrorism."

"I am deeply saddened to hear of the appalling attacks this morning in London," said Secretary General Jaap de Hoop Scheffer.

The NATO head, speaking from the alliance's headquarters in Brussels, said: "I condemn in the strongest terms these attacks, which underline the need for the international community and members of the Alliance to remain united in the fight against terrorism."

"I know I speak on behalf of all NATO allies when I express oursympathy for and solidarity with the British people... There can be no justification for such heinous crimes," he said.

In Moscow, Russia's foreign ministry said the country categorically condemns the attacks in London.

"The foreign ministry of the Russian Federation categorically condemns the terrorist acts in London that resulted in human losses," foreign ministry spokesman Alexander Yakovenko said in a written statement.

French President Jacques Chirac told British Prime Minister Tony Blair that Britain had France's "total solidarity" following the fatal bomb blasts in London.

"The president of the Republic told the British prime minister of his horror at the tragic events in London and expressed his sad condolences," a presidential spokesman said in Gleneagles, Scotland, where Chirac is attending a Group of Eight summit hosted by Blair.

"He told him of the total solidarity of France and of the French people," said the spokesman.

In Madrid, the Spanish government strongly condemned the "savage attacks" that rocked London and expressed its solidarity with the British people and government.

"Spain, which has suffered for years from the scourge of national and international terrorism, offers its unconditional help to the United Kingdom to pursue the criminals who have carried out a shameful attack against a city which was celebratingafter being chosen to host the Olympic Games in 2012," a government statement said.

The government "condemns with all its force the savage attacks that took place in London and expresses its solidarity with the people of London, the government, the authorities and the British people," it said.

The Spanish government expressed "its condolences to the families of the victims and issues an appeal to all those who believe in freedom and peace against barbarity and terrorism."

Irish Prime Minister Bertie Ahern, who is visiting the Vatican on Thursday, condemned the London blasts as "a black mark on society" and said such acts of terrorism would not affect decisions by the Group of Eight.

"This is terrorism and violence perpetrated against ordinary people ... it's just a black mark on society, a devastating blow against people," he told reporters minutes after meeting Pope Benedict at the Vatican.

"This is a huge emergency. A terrible, sad day," he said.

"What satisfaction do people get out of that? Will this mean that the G8 leaders will make a different decision than they wouldhave made yesterday?. It won't," Ahern said.

"This is all wanton violence. What does this all mean, killinginnocent people who were probably on their holidays, going shopping around London for the day," he said.

Italy's President Carlo Azeglio Ciampi has sent a message of condolence to British Queen Elizabeth II.

"The loss of so many human lives and the devastation caused by this barbarity and terrorism arouses the repugnance and indignation of all Italians," said Ciampi in the message.

Italian news agencies also quoted the country's European Commissioner France Frattini as saying that the explosions in London were a terrorist strike against Europe.

"What has happened is the tragic confirmation that terrorism strikes once more at the heart of Europe," Frattini was reported as saying by the Apcom and ANSA news agencies.

"It's necessary to immediately activate coordination between intelligence and police service and offer England all the help possible," Frattini, Europe's commissioner for justice and help affairs was quoted as saying.
