Pro-ISIS and anti-Semitic graffiti in DC?

They claim that there is pro-ISIS graffiti in DC.  Look at the images. There is certainly pro-Bashshar Al-Asad graffiti but no pro-ISIS.  And how would support for Bashshar be reconciled with support for ISIS?  But I think that they think that Allahu Akbar is a distinctive ISIS slogan.  Also, what is anti-Semitic about the graffiti--at least in the accompanying pictures?  #Idiots_of_Western_media
