Jihad Watch reader RW kindly sends in these photos taken outside Bow Central Mosque in the East End of London.
The top picture is a side shot of the Bow Central Mosque. You can see the blue graffiti on the bridge pillar across the street from the mosque.
The second picture shows the graffiti itself, possibly painted with a crude stencil, on the pillar. Does the graffiti come from someone connected with the mosque? Not necessarily. But mosquegoers must see it every time they exit the mosque. They could paint it over. If they wanted to.
