The Islamic State has released a new propaganda video showing two deaf fighters speaking in sign language and urging more Westerners to join the terror group . The video is titled 'From Who Excused [ sic ] To Those Not Excused ' - suggesting that disability is no excuse for not serving for ISIS . In the five minute clip the two men , who are deaf-mutes and brothers , are shown working as traffic police in Iraq 's second city Mosul , which has been under ISIS control since last summer . Scroll down for video . Two deaf-mute brothers who claim to be fighting for ISIS in Iraq have taken part in the group 's latest propaganda video , in an attempt to recruit more people with disabilities to fight for the terror group . The footage , which features the Islamic State flag in the top right hand corner , also shows them working for the traffic police in Mosul , in an attempt to depict an normal life as part of the terror group 's Caliphate . Speaking in sign language with English and Arabic subtitles , one of the men says : ' I am a deaf mute who works in the traffic police in the Islamic State with my brother Abu Abdur-Rahman . 'As for my message to the apostate peshmerga ( Kurdish fighters ) we will strike you soon , by Allah 's permission . I am living in a land in which Allah 's sharia is established . ' Wearing black jumpsuits , ammunition pouches and carrying what appear to be M16 assault rifles , the pair also speak about their desire to 'slaughter ' their enemies including Britain , America , France and Italy , saying 'you will not stop our advance ' . The fighters also threaten Saudi Arabia , Kuwait , Qatar and those who have allied with the West , vowing to destroy them . In the final section of the slickly produced and professionally edited film , the brothers are shown assembling simple rocket launchers which they claim are used to fire at Kurdish fighters . The weapons consist of little more than crudely made explosives balanced on a metal frame which is tilted upwards and held in place using a few rocks . In the last seconds of the film , which features the Islamic State 's logo in the top right hand corner , one of the men presses a trigger , launching the rockets . The last seconds of the film show the pair wiring up and launching two crude missiles which they claim are being aimed at Kurdish peshmerga fighters . Alex Kassirer , a researcher at Flashpoint Intelligence , who spoke to NBC News , said the video 'represents an attempt by the group to recruit other physically or otherwise impaired individuals , as well as demonstrates the multifaceted responsibilities of those in its ranks . ' ISIS 's ability to recruit western jihadis using online propaganda films and its monthly magazine , Dabiq , is well documented , and the films often feature fighters speaking about their daily lives , in an attempt to present life under the extremist Caliphate in a positive light . However this is thought to be the first film which deliberately features disabled people in an attempt to recruit more from Europe and the West .
