David Cameron has declared he wants to catch Jihadi John 'dead or alive' as he promised to double the number of drones targeting ISIS. The Prime Minister said he was ready to 'beef up' the SAS to find and kill terrorists plotting attacks in Britain. It comes after he authorised a drone strike to take out ISIS poster boy Reyaad Khan in Syria without getting approval from Parliament. The Tory party conference gets underway in Manchester today, with a heavy emphasis on security. Mr Cameron signalled that the intelligence and military services need more resources to carry out the surveillance needed to find and kill fanatics. He told the Sunday Telegraph that the UK will buy a fleet of 20 new Protector drones capable of targeting IS extremists in Iraq and Syria. Mr Cameron said: 'One of the biggest threats we have to respond to is that terrorist threat and that means a lot of things in terms of obviously domestic security and our intelligence services. 'But it also means making sure that we have the military equipment and resources we need - so seeing an enhancement of our Special Forces and particularly on the issue of surveillance aircraft.' Last month Mr Cameron stunned the House of Commons with the revelation that for the first time in modern history the UK had carried out a military strike in a foreign country outside of a war. A drone killed former Cardiff schoolboy Reyaad Khan, 21, who was accused of plotting bloody attacks on the streets of Britain Two other ISIS militants, including British national Ruhul Amin, were also killed in the attack on Khan on August 21. No civilians died. Government sources suggested there were up to a dozen British Islamist fanatics including ISIS killer Jihadi John were on government 'kill list' to be targeted in precision airstrikes. Mr Cameron insisted that more terrorists will be targeted by RAF drones, adding that he still wants the Jihadi John captured 'dead or alive'. Setting out the new drones being made available to deal with ISIS, Mr Cameron said: 'We have at the moment a drone fleet of 10 Reapers and what we are going to be doing is actually replacing that with twice as many with a new updated piece of equipment - called Protector - which will be more than doubling our fleet to keep us safe and to give us the intelligence and information and potentially give us the capacity to hit people who are potentially planning to hit us.' Asked whether there would be more missions in Syria targeting British jihadists, following the strike which killed Britons Reyaad Khan and Ruhul Amin, Mr Cameron said: 'It's obviously a last resort. It's only the right thing to do if there are no other avenues you can take. 'What we try to do is stop people travelling to these regions, confiscate their passports, work with local government to have them arrested or detained. We try and take every step we can but at the end of the day we have to keep the British people safe from terrorist threats.' Mr Cameron made clear that security, and the defence of the country, would be one of the key issues of the conference. That will be seen as a bid to exploit Labour's divisions after Mr Corbyn defied many Shadow Cabinet colleagues by calling for Britain's Trident nuclear deterrent to be ditched. Mr Cameron also disclosed that he would not be rushed into naming the date of the EU referendum and said he was not frightened by the prospect of voters opting to leave the union after some polls showed growing support for an 'out' vote.
