The international community has been worried over the humanitarian situation in Iraq.
Nearly 30,000 Yazidis have fled into the mountains for fear of being killed.
Islamic States militants have been targeting Christians and Kurds for a couple of weeks now and those who fled may be in even greater danger with lack of food and water and other basic necessities.
While deliberations continue as to giving the Kurds weapon to fight insurgents, Britain says its major concern is that the militants could grow strong enough to target people on the streets of Britain, unless it takes action.
This usually involves the use of all resources – aid diplomacy and military prowess to help bring about what it calls a stable world.
The British Prime Minister, David Cameron said in an interview, that a humanitarian response to Islamic state militants was not enough and they could only be kept in check via a firm security response.
The militants have reportedly taken over large parts of northern Iraq and Syria in the past few weeks. But Kurdish forces, supported by US airstrikes, have reclaimed Mosul Dam, important to Iraq’s electricity generation.
Mr Cameron’s fear, is that if intense counter-attacks are carried out, then it is only a matter of time before the terrorist movement will target the UK.
The UK has been involved in providing supplies to people stranded as a result of the fighting, providing a series of air drops, especially for those who have fled towards the mountains.
But Mr Cameron will not tolerate any sympathy towards s militants from Britons. He has suggested that anyone walking around with Isil flags or trying to recruit people to their terrorist cause, should be arrested.
He has also stressed his perception of the Iraqi crisis,which he did not see as a war on terror, but as a battle between Islam on the one hand and extremists who want to abuse Islam on the other.
The group is estimated as having about 400 recruits from the UK, and some 69 people suspected of Syria-related Jihadist activists have been arrested in the UK.
