Mossad tells Brits: Same explosives likely used in Tel Aviv and London blasts

The German newspaper Bild am Sonntag reported that Mossad informed British security authorities that the explosive material used in the attack on Mike's Place pub was probably used in the bombings in London last Thursday. The Mossad office there received advance notice about the attacks, six minutes before the first blast, confirming an earlier report by AP which Israeli officials denied.
