Tens of thousands of propaganda leaflets have been dropped at the centre of the Islamic State power base in a bid to destabilise the extremist group . The Pentagon-led operation saw 60,000 leaflets depicting a cartoon of ISIS recruits dropped in Raqqa in Syria - considered to be at the centre of IS operations . Each leaflet depicts would-be jihadists being fed into a meat grinder by malevolent militants , with blood on their hands . The line of recruits cower from the militants as they attempt to entice them towards the grinder . Propaganda leaflets , depicting ISIS recruits being fed into a meat grinder , have been dropped by the Pentagon in Raqqa , the self-proclaimed ISIS capital in Syria , in a bid to destabilise the extremist group . The propaganda , created by Military Information Support Operations , is aimed at destabilising connections within ISIS . 'It 's trying to set the stage for an internal uprising against ISIS , ' Nicholas Heras , an expert on ISIS at the Center for a New American Security told USA Today . The leaflets were dropped by an Air Force F-15E Strike Eagle fighter , which dropped a specialized leaflet-dispenser bomb for the first time in Syria , according to Air Force spokesman Colonel Tadd Sholtis . A sign on the leaflet says 'Daish Recruiting Office ' with 'Daish ' another word used to describe Islamic State . The same word appears on the meat grinder . Another sign reads 'now serving 6001 ' , and the new ISIS recruit at the front of the queue is shown dropping his ticket number as he is encouraged to step forward by one of the militants . Yesterday the US launched airstrikes against targets in Tikrit in Iraq to support Iraqi ground forces trying to push IS militants out of the country . The strikes began on Wednesday and are understood to be ongoing . The US has hundreds of military advisers in Iraq helping its security forces plan operations against the Islamic State , which occupies large chunks of northern and western Iraq . In contrast to traditional drops , forces used a specialised leaflet-dispensing bomb to drop the propaganda . Iraqi security forces and Shiite militias have battled ISIS militants in Tikrit , where smoke was seen yesterday . The leaflet drop is said to be a softer tactic being used by American forces to try and destabilise ISIS , as news of problems within the group emerge with some fighters reluctant to take part in fighting in Kobani , on the border with Turkey . Propaganda is already widely used to give daily updates about air strikes in Syria , but the Pentagon has typically kept its releases more low key . ISIS also makes use of propaganda itself , producing weekly and daily news bulletins about successful strikes and action in the country . This week the group also produced an 'idiots guide ' to travelling to Syria . Last year supporters of ISIS were arrested for giving out promotional leaflets in Oxford Circus in London , aimed at encouraging people to leave Britain for Islamic State .
Specialised 'leaflet-dispenser bomb ' was dropped in ISIS base in Syria . Leaflet depicts cartoon of would-be jihadists being fed into a meat grinder . Around 60,000 leaflets were dropped in bid to destabilise extremist group . Plan is to take advantage of internal disputes within IS with the cartoon .
