LONDON July 7 (Xinhuanet) -- British Foreign Secretary Jack Straw said Thursday that the bombing in central London earlier in the day had "the hallmarks of an al-Qaeda related attack".

    Four explosions in the London underground railways and on a bus during morning rush hour killed at least 37 people and injured more than 300.

    However, the London Metropolitan police said they still need further evidence to confirm whether the terrorist attacks were committed by al-Qaeda.

    Earlier Thursday, a Muslim website announced to be responsible to the bombings in London.

    British Prime Minister Tony Blair rushed to London from Scotland where the world 8 riches countries are gathering to discuss topics of aid Africa and climate change to handle the emergency.

    He said after a meeting with ministers and officials in London Thursday afternoon that in a televised address from 10 Downing Street "it is through terrorism that the people that have committed these terrible acts express their values and it is right at this moment that we demonstrate ours."

    He said in a televised address to the nation that the perpetrators of the deadliest peacetime attacks in Britain's history acted "in the name of Islam" and he vowed to "bring the responsible to justice".

    "We know that these people act in the name of Islam but we also know that the vast and overwhelming majority of Muslims here and abroad are decent and law abiding people who abhor terrorism every bit as much as we do."

    London's public transit system is heavily used by the city's 8 million residents. Screening every passenger for explosives, even if it were possible, still wouldn't eliminate the terrorist threat, experts said Thursday. Enditem
