Last month two men from Cardiff and one from Aberdeen featured in an online recruitment video by Isis urging western Muslims to join the fighting with the Islamic State in Iraq and Greater Syria. On Monday Theresa May warned the Home Secretary of the impact on families when loved ones join fighting. 400+ people from the UK have travelled to Iraq and Syria and a new campaign, Families Against Stress and Trauma (FAST) was launched this week urging people to stop their relatives from travelling to join wars. Mrs May said, ‘This campaign addresses one of the most significant issues facing communities up and down Britain – the extremely damaging effect of young people choosing to travel to Syria and Iraq.’ Mrs May added, 'I am clear, in relation to people who are going to Syria and returning as terrorists. The Government will take action.’
