ISLAMIC STATE (Isis) claimed responsibility today for an attack on a Roman Catholic church in the Turkish city of Istanbul that left one person dead.

The jihadist death cult said in a statement that it had “attacked a gathering of Christian unbelievers during their polytheistic ceremony” inside the Santa Maria church in the city’s Buyukdere district.

The man killed was a 52-year-old Turkish citizen who was out taking a walk at the time when he went into the church, where Sunday Mass was being held.
