Kenyan President Mwai Kibaki Thursday sent a message of condolence to British Prime Minister Tony Blair following a series of bomb attacks on London's transport network which killed more than 30 people and injured about 350 others.

In a statement issued here, the Kenyan leader denounced the acts of terrorism against innocent civilians in London, noting that the atrocities were gross violation against the right to live and freedom to live without fear.

"Indeed, the heinous attacks against humanity should rekindle our joint efforts against terrorism and serve as the driving force for the world to unite against the vice," said Kibaki whose country has suffered twice as a result of terrorism.

The death toll was expected to rise and London hospitals reported many people in critical and serious condition.

Three of the blasts took place in the city's subway system and one more hit a double-decker bus, all at the height of morning rush hour.

British Prime Minister Tony Blair, who has returned to London from the G8 summit in Scotland, has described the attack as " barbaric."

Kenyan Government Spokesman Alfred Mutua said the east African nation was still in contact with its embassy in London to establish if there were Kenyan casualties in the terror attack.

A previously unknown group, the "Secret Organization group of al-Qaeda Organization in Europe," has claimed responsibility in a website posting.

The authenticity of the claim could not immediately be verified.
