BREAKING: Scotland Yard says it got a warning before the attack and told Israel.
Fox News has carried a report from AP saying that Scotland Yard had prior knowledge. Israeli News is reporting that "The Israeli Embassy in London was notified in advance, resulting in Finance Minister Binyamin Netanyahu remaining in his hotel room rather than make his way to the hotel adjacent to the site of the first explosion, a Liverpool Street train station, where he was to address and economic summit."
