AP has what I think is the original version of this story:
Netanyahu Changed Plans Due to Warning
It's by Amy Teibel, a very anti Israeli / pro Islamist AP writer. She has a habit of providing anonymous quotes of outrageous Israeli behavior for PA propoganda purposes.
It's interesting to me that this story was ready to go within a very short period of time after the blasts. I wonder if it was pre-written? I bet a good computer forensics team could check her computer and find out. If it was pre-written that would just about convict her as an accomplice in this terrorist act.
Here's the bulk of the article from the link above. Notice how she makes her outrageous claims with no source then provides a seperate quote from an Israeli about a related subject, trying to imply that the first (fake) quote was from that person as well:
JERUSALEM - British police told the Israeli Embassy in London minutes before Thursday's explosions that they had received warnings of possible terror attacks in the city, a senior Israeli official said.
Israeli Finance Minister
Benjamin Netanyahu had planned to attend an economic conference in a hotel over the subway stop where one of the blasts occurred, and the warning prompted him to stay in his hotel room instead, government officials said.
Foreign Minister Silvan Shalom said he wasn't aware of any Israeli casualties.
Just before the blasts, Scotland Yard called the security officer at the Israeli Embassy to say they had received warnings of possible attacks, the official said. He did not say whether British police made any link to the economic conference.
The official spoke on condition of anonymity because of the nature of his position.
The Israeli Embassy was in a state of emergency after the explosions in London, with no one allowed to enter or leave, said the Israeli ambassador to London, Zvi Hefet.
All phone lines to the embassy were down, said Danny Biran, an Israeli Foreign Ministry official.
The ministry set up a situation room to deal with hundreds of phone calls from concerned relatives. Thousands of Israelis are living in London or visiting the city at this time, Biran said.
Amir Gilad, a Netanyahu aide, told Israel Radio that Netanyahu's entourage was receiving updates all morning from British security officials, and "we have also asked to change our plans."
Netanyahu had been scheduled to stay in London until Sunday, but that could change, Gilad said.
