AL-JAZEERA television said last night it had received a videotape in which al-Qaida claims responsibility for the July bombings in London.

A statement posted today on an Islamic website in the name of an al-Qaida-linked group claimed responsibility for latest blasts targeting London’s transport system.

An al-Qaida-linked group posted an internet statement today claiming responsibility for the string of bombings that rocked London and killed at least 49 people, promising more attacks in London, which it described as the “capital of the infidels”.
