At the start of this month US President Barack Obama announced a new task force to target IS leaders and gather intelligence. Over the weekend the UK Times newspaper trumpeted the role of British SAS forces in combating IS fighters in Libya. The New Zealand Labour leader Andrew Little announced yesterday said he would support sending New Zealand special forces into Iraq if the conditions are right.
