LONDON (Agencies) - The new head of Israels secret service, Mossad, is ready to apologise for the use of forged British passports during the assassination of a leading Hamas leader in Dubai, reports The Sunday Telegraph. Tamir Pardo, who took over as Mossads chief earlier this month, will also promise that Israeli agents will never again be allowed to use fake British documents during operations abroad, the paper said. The paper quoted Mossad sources as saying that he will make the pledges to officials in London and, he hopes, in private meetings with the foreign secretary, William Hague, and the home secretary, Theresa May, as part of an urgent drive to rebuild relations with the UK government, thrown into disarray earlier this year. In March Britain expelled Mossads station chief in London, a key foreign posting, after an investigation blamed Israels secret service for cloning 12 British passports that were found among 26 forged identity documents used by the hit squad that murdered Mahmoud al Mabhouh in January. David Milliband, then foreign secretary, told MPs that Israel had shown a profound disregard for British sovereignty, adding: The fact that this was done by a country which is a friend, with significant diplomatic, cultural, business and personal ties to the UK, only adds insult to injury. Pardo, 57, who was deputy director of Mossad for the past three years, is said by a source involved in the planning of the operation to have argued against using British, Irish and Australian passports for the team sent to murder al Mabhouh in his hotel room. But Meir Dagan, the Mossad chief who stepped aside this month, insisted that with so many visitors from those three countries travelling to Dubai, their passports would not be scrutinised. After the Dubai debacle, the source said, Pardo warned Dagan that the whole business will come home to haunt us. Pardo, known as T to fellow Mossad officers since he joined the service 30 years ago, is said to regard the expulsion of the services top official in London as a blow to the organisation. Since then official collaboration between Mossad and the British agencies responsible for security at home and abroad, MI5 and MI6, has been badly dented, to the detriment of both. But Dagan bluntly refused to apologise over the use of the faked passports let alone offer the guarantee demanded by Britain that the theft would not recur. Pardos apology and pledge during a visit to London that is expected early in January would be the first official acknowledgement by Israel that it was behind the assassination of the Hamas leader in Dubai. He also intends to increase Mossads role in Yemen and to spearhead the hunt for al-Qaedas new chief of military operations, Saif al-Adel, who Mossad believe is based in Somalia. The paper also said that Mossad has agents in Afghanistan tracking the Taliban.
