Nigel Farage has called for any migrants rescued from the Mediterranean to be sent back to Africa. The Ukip leader said 'millions' of refugees could arrive on boats in Europe over the next few years unless they are intercepted and turned back now. Mr Farage urged Prime Minister David Cameron to resist pressure at an emergency summit of EU leaders in Brussels tomorrow for Britain to take in large numbers of refugees brought across the Mediterranean by people-smugglers. Scroll down for video . The Ukip leader, on ITV's Lorraine this morning, said 'millions' of refugees could arrive on boats in Europe over the next few years unless they are intercepted and turned back now . He insisted the UK could not take more than 'a few thousand' genuine refugees. His comments came as experts warned that up to 30,000 migrants, including 2,500 children, could be killed this year unless the crisis is tackled. Up to 950 people are believed to have drowned in a shipwreck off the coast of Libya on Saturday, according to the Office of the United Nations High Commissioner for Refugees. Just 28 people are known to have survived the tragedy, described by UNHCR as 'the deadliest incident in the Mediterranean we have ever recorded'. The Ukip leader's comments came as experts warned that up to 30,000 migrants, including 2,500 children, could be killed this year unless the crisis is tackled . Up to 950 people are believed to have drowned in a shipwreck off the coast of Libya on Saturday, according to the Office of the United Nations High Commissioner for Refugees . Europe has been urged to copy Australia's military-led 'stop the boats' policy to avoid migrant tragedies in the Mediterranean. Australian PM Tony Abbott – who sends naval gunboats to turn back asylum seekers before they reach Australia – said the EU should 'urgently' follow his lead. His hardline policy has proved controversial but Mr Abbott said it was the only way to prevent disasters such as the loss of 900 lives when a fishing boat capsized on Saturday night. He said: 'The only way you can stop the deaths is to stop the boats. 'That's why it is so urgent that the countries of Europe adopt very strong policies that will end the people-smuggling trade across the Mediterranean.' Conservative Mr Abbott won power in 2013 on a 'stop the boats' pledge, and not a single one has breached his ring of steel in 18 months. Operation Sovereign Borders involves the Australian Navy intercepting boats filled with migrants at sea, and either turning them back or towing them back to where they came from. Mr Abbott has previously said he was sick of being lectured to by the United Nations over Australia's obligations to refugees, saying his policy was the 'most decent, most compassionate' solution. In the Mediterranean, callous people smugglers have been exploiting a willingness by European nations to rescue migrants rather than send them back. Last year, Italy scaled back its rescue operations because it feared they were only encouraging migrants to gamble with their lives. But the horrific loss of life over the past week in a spate of migrant shipwrecks has prompted calls to urgently reinstate the rescue missions. EU leaders including David Cameron are meeting tomorrow in what charities are calling a 'life or death' summit to solve the problem. The death toll from capsizing disasters stands at 1,727 so far this year - 30 times higher than the 56 fatalities by April 21 last year, according to the International Organisation for Migration (IOM). At its recent rate the total for this year could reach 30,000. The Prime Minister and other European leaders are under mounting pressure to come up with a plan to stem the rising number of migrants killed trying to cross the sea for a better life in Europe. Mr Farage said Britain bore a burden of responsibility for the flow of migrants heading out of north Africa because of its military interventions in countries like Libya and Iraq. He said he was happy for Royal Navy ships to take part in search and rescue operations in the area, and for funds currently spent on overseas aid and EU contributions to be diverted to help people in the countries involved. But the Ukip leader told BBC1's Breakfast: 'The big message has to come from Italy, the big message has to come from Greece. The Australian prime minister said it yesterday: unless we send a message that we are not going to unconditionally accept unlimited numbers of people, they will keep coming. That's a decision that's got to be taken by the southern Mediterranean countries. 'What is the message from Italy and Greece? Is it that anybody that comes will be accepted? Because if it is, millions of people could be coming over the next couple of years. 'I'm suggesting that they should be making sure that those people coming in vessels that are not seaworthy should be put into vessels which are seaworthy and taken back to where they came from. 'There may be some cases where people genuinely need refugee status and if Britain has to give a helping hand and give, for example, some Christians refugee status ... then fine.' Asked how many refugees he would be willing for the UK to take, Mr Farage said: 'I would suggest a few thousand, because we as a country can't take unlimited numbers of people. The Prime Minister is going to be under intense pressure on Thursday for us to take really very big numbers and I am afraid we simply can't do that.' Mr Cameron has faced criticism for cutting funding for search and rescue operations in the area. The Times said British military chiefs were preparing to offer one of the country's biggest warships to help tackle the refugee crisis. HMS Bulwark, a 176-metre launchpad for helicopters and small vessels which protected London during the 2012 Olympics, is understood to be among the options being considered by ministers. An MoD spokeswoman said it was 'looking at options but no decisions have been taken'. The charity Save the Children has called on EU leaders to restart search and rescue operations off the coast of Italy within 48 hours, on the scale of the previous, and far larger, Italian-led Mare Nostrum operation. Around 1,300 people are believed to have drowned in the past two weeks while trying to reach Europe in make-shift boats launched by people smugglers from Libya – with up to 950 perishing off the Italian island of Lampedusa over the weekend alone . Chief executive Justin Forsyth said: 'EU leaders hold the lives of thousands of desperate people in their hands when they meet tomorrow. 'With every day that they prevaricate and delay restarting search and rescue operations, the risk grows that more people will die as they try to reach Europe. 'We cannot allow 2015 to be the deadliest year in the Mediterranean yet. We must get agreement at Thursday's meeting to scale search and rescue back up to 2014 levels. 'Even one boat that sinks is one too many, but the escalating number of people dying off Italy's shores brings home the urgent need to act.' Maurice Wren, chief executive of the Refugee Council, said the response to events in the Mediterranean was 'inadequate' and Europe had to 'raise its game'. Two alleged people smugglers, including one believed to have been the captain of the ship which was wrecked at the weekend, have been detained by Italian authorities, according to reports. It has been claimed the boat capsized after accidentally colliding with another ship which came to its aid. Boris Johnson this morning called for more to be done to help the fleeing migrants . British special forces should be sent into Libya to lead Europe-wide action to tackle human traffickers, Boris Johnson has suggested. The mayor of London insisted action was required to 'choke off the problem at source' to stop migrants being put on to unseaworthy vessels to travel across the Mediterranean Sea from north Africa. He said: 'The first thing to do is to stop the people who are trafficking in human lives and I think sending over a warship - or whatever we're going to do - is entirely right. 'Myself, I'd like to see a real commitment to getting to grips with these people and round...' Host Nick Ferrari asked if this involved sending military personnel into Libya, Mr Johnson said: 'You need to do something about it.' Mr Ferrari countered: 'You're saying special forces into Libya.' Mr Johnson replied: 'I'm a long way away from the discussions about this but there are clearly some very highly organised and ruthless people who are sending people to their deaths in the Mediterranean. It seems to me that is something that should be the subject of concerted European response led by Britain.' Mr Ferrari interjected: 'We've got it - the SAS and SBS into Libya.' Mr Johnson said: 'I don't see why not, I don't see why not.'
