Officials in Pakistan have confirmed that one of the men who carried out last week's bomb attacks in London had previously visited Pakistan.

So far though they have not been able to pinpoint the movements of the bomber, Shehzad Tanweer, in the country or say who he met.

They say he visited Pakistan twice, spending a total of four months there.

On Wednesday Tanweer's uncle said he had been to Pakistan and attended an Islamic school, or madrassa.

Longer period

According to knowledgeable sources, Pakistani intelligence and investigation agencies are working flat out to accommodate British demands for leads on any of the three London bombers of Pakistani descent.

The sources confirmed to the BBC that Shehzad Tanweer entered Pakistan on two occasions.

They say the first occasion was a brief visit, possibly at the end of 2003, then for a longer period later.

His entries were tracked by a system called Pisces in which everyone who comes into Pakistan legally, via any port of entry, is photographed.

The sources say agencies in Pakistan are still trying to discover Tanweer's movements inside the country.

The sources say the other two bombers of Pakistani descent had not been picked up on the Pisces system.

So if they did enter Pakistan after 2002, when the system was introduced, they did so illegally.

The sources said little was known about the bombers in Pakistan, but more may be known about the people they may have been in contact with.

That, and efforts to ascertain whether there was a Pakistan-based mastermind, will be the focus of investigations in the coming days and weeks.

The sources also said reports that British anti-terrorism, or intelligence investigators, were on their way to Pakistan were untrue."
