The British Prime Minister, David Cameron, has told the White House that he intends to stand shoulder to shoulder with President Obama as the United States steps up its global hunt for leading jihadists, The telegraph reported on Sunday. According to the report, it is understood that the Prime Minister has given his approval for the elite British troops to be used beyond Afghanistan in order to "decapitate" the al-Qaeda leadership. Britain already has counter-terrorist teams located in the North West Frontier Province in Pakistan and in Yemen, where they are responsible for training indigenous troops in counter-insurgency, counter-IED and counter-intelligence techniques. Defence sources have said that the hunt for leading jihadists, such as Ayman al-Zawahri, al-Qaeda's second-in-command, and Mullah Omar, the former Taliban leader, will continue in the Afghanistan-Pakistan border region. But it is understood that the US and British special forces could also be deployed to conduct strike operations in Yemen. The SAS are already working closely with the US Special Forces in Afghanistan where they have spent the last year conducting hundreds of search and destroy operations in a bid to break the back of the Taliban. But a senior officer warned that despite the death of al-Qaeda's leader, the terrorist organisation will still remain a potent threat for years to come. He said: "Al-Qaeda has lost momentum, and the death of bin Laden will only make it more difficult for the organisation to conduct attacks. It will hard for al-Qaeda to find another iconic figure but despite this we should avoid talk of 'winning'. "This is a useful military event which should be used to help deter the threat. It demonstrates the reach and persistence of the US government to achieve justice. But, overall, I believe this is a case of 'situation, no change'. This was a significant event during a long campaign." In a separate development a senior defence source has also revealed that Britain would have launched the same military action as the United States if the government had located the whereabouts of Osama bin Laden. The source said the SAS would have conducted the same type of "kill not capture" operation as that executed by members of Seal Team 6 last week. Speaking on the condition of anonymity, he added that the Government would have also sanctioned the bombing of the house in which the leader of al-Qaeda was hiding even if there was a high probability of killing innocent civilians. The prime minister's approval for such a mission would be required and a legal analysis of the action would have been undertaken, but he added: "Given the threat posed by Osama bin Laden and the fact that he has managed to evade capture for so long there was really no alternative." The officer added that Britain had "war-gamed" scenarios in which the location of Osama Bin Laden or other senior Taliban figures had been discovered to "test" what action would be taken. The officer added: "If we have been provided with 'grade A' intelligence which said that he (bin Laden) was at a certain location for a limited period of time, we would have bombed the location even if it had meant that there was a high possibility of collateral damage."
