Joel Rosenberg, who used to work with Bibi, says in an e-mail to his address book:

I have just spoken to a source very close to Israeli Finance Minister Benjamin Netanyahu. Netanyahu was scheduled to speak later today at an economic conference in a London hotel directly above the site of one of the subway explosions.
Netanyahu and his security team are now in a “lock down” in London as the city reels from at least four explosions this morning. A new report I just got say there at least 20 dead and the publicly reported death toll will soon soar.
British Prime Minister Tony Blair has confirmed the explosions were an act of “terrorism” which he called “barbaric.” President Bush has vowed to hunt down those “who have evil in their hearts.”
“The explosion happened just beneath the hotel at the same time the meeting with businessman interested in investing in Israel was expected to begin,” said an aide to Netanyahu.
There were published reports early this morning that Scotland Yard officials contacted the Israelis minutes before the attacks to warn them of imminent terrorist strikes.
My sources in the Israeli Government are denying those reports. They say the Israeli Embassy and the Netanyahu security team received reports immediately AFTER the first explosion, warning Netanyahu not to go to the hotel.
“There was no early information about terrorist attacks,” said Foreign Minister Silvan Shalom on Israel Army Radio. “After the first explosion an order was given that no one move until things become clear.”
