IN TOWNS, desert camps and cyber space, Islamic State will be wiped-out, a core coalition of nations vowed yesterday as they revealed half the terror group’s top command have been killed.

And Australia’s assault on terrorism both at home and abroad was singled out by US Secretary John Kerry as an example to other nations of the commitment to the now global fight against the jihadi group and its sympathisers.

Mr Kerry was joined by Iraqi Prime Minister Haider al-Abadi and officials from 20 “core” countries including Australia for a closed-door high security meeting at Lancaster House in central London.

The American said the fight was being won, but the meeting of core Coalition nations aimed at refining the coordination of the assault on the terror group.

He then gave a detailed snapshot of the “multiple lines” of attack on ISIS including revealing that 50 per cent of its commanders had been killed along with thousands of their fighters both on the ground and through nearly 2000 precision air strikes by the coalition including American and Australian fighters.

With the aid of intelligence and security services, would be foreign-fighters trying to enter to and from the battleground through “transit routes” including Bulgaria, Romania and Turkey had been stopped.

“We are taking out (ISIS) fighters in the thousands thus far, single digits but thousands and 50 per cent of their top command have been eliminated, hundreds of vehicles and tanks which they captured have been destroyed, nearly 200 oil and gas facilities they were using have been eliminated from their capacity to sell and get revenue from them, as well as more than 1000 of their fighting positions, check points, buildings, barracks in Iraq and Syria,” he said.

“Foreign fighter networks have been broken up in Austria, Malaysia, Kosovo and in other countries foreign fighters have been prosecuted in Germany, Australia and the UK. Saudi Arabia has now issued formal decrees criminalising (ISIS) … and we have seen fatwas now issued by top religious leaders in Egypt and Saudi Arabia declaring (ISIS) a direct threat to Islam.

Mr Kerry said 700sq km of land had been reclaimed from the enemy in the five months of the war and training by the coalition was being ramped up to help Iraq create 12 new battalions with US forces to further establish training camps in Qatar, Turkey and Saudi Arabia for Syrian Opposition forces.

He said the ISIS capital of Mosul was also showing signs of descent with coalition’s cut in revenue affecting the way ISIS pays and feeds its troops.

“We are working with coalition partners to establish operation rooms to combat their (ISIS) social media presence and be able to message in real time so there is an enormous amount that is happening and that is happening in a matter of months and the meeting today has been to take stock of those,” Mr Kerry said.

Australia has more than 200 special forces in Iraq and the Iraqi prime minister said all coalition forces currently in-country would be increasing their work with local forces to combat the enemy at the gates.

Mr al-Abadi said his armies needed more weapons to which Mr Kerry said significant amounts of M16 rifles and ammunition was en route. He also asked for greater financial support after the government in Baghdad saw a collapse in its revenues as a result in the slump in the oil prices.

“This has been disastrous for us. We don’t want to see a reverse of our military victory due to our budget and fiscal problems,” he said.

The meeting brought together representatives from among others Australia, Canada, France, Italy, Belgium, Spain and Netherlands as well as Arabic states including UAE, Qatar, Bahrain, Jordan, Kuwait and Turkey.

“This is not a Syrian problem, its not a Iraqi problem (ISIS) is a global problem and it demands a coordinated comprehensive and enduring global response and that is what we are doing today,” Mr Kerry said.
