They have issued a rambling and almost incomprehensible statement in poor French: an English translation is available on the Spectator website here.
These nutcases do not appear able to understand the distinction between "crusaders" and a football team or people eating a quiet meal in a restaurant; or between a rock concert and a "profligate prostitution party." They describe the victims of the attack as "apostates" when they could have no idea what religion the people concerned followed or whether any of them were former Muslims who had renounced or attacked that faith.
As no casualty list has yet been published yet we can have no idea whether any of the dead were Muslims. It is a good chance that a few of them will indeed have been followers of the Islamic faith but fairly unlikely that there will have been any who on the most strict Islamic interpretation of the Qu'ran were guilty of apostasy,
If they were not able to obtain and use explosive belts and automatic weapons, if they had not massacred thousands of people in Iraq and Syria, the utter lunacy of the DAESH death cult and its' members would be hysterically funny.
The messages issued condemning the attack include many from Muslims.
For example, in a statement entitled
"Horrific Attacks in Paris: Muslim Council of Britain Responds,"
the Muslim Council of Britain's Secretary General Dr Shuja Shafi issued the following statement:
“The attacks once again in Paris are horrific and abhorrent, and we condemn this violence in the strongest possible terms. My thoughts and prayers for the families of those killed and injured and for the people of France, our neighbours.
This attack is being claimed by the group calling themselves ‘Islamic State’. There is nothing Islamic about such people and their actions are evil, and outside the boundaries set by our faith.
This week we have once again witnessed outrageous attacks be that in Beirut earlier in the week or Paris today – there is no justification for such carnage whatsoever. We hope those responsible are brought to justice and face the full force of the law.”
Muslims around the world also condemned the Paris attacks, including the President of Iran, Hassan Rouhani, who condemned the attacks as a “crime against humanity.” He said
"In the name of the Iranian people, who have themselves been victims of terrorism, I strongly condemn these crimes against humanity and offer my condolences to the grieving French people and government."
