Good. The more of their own that IS kills, the fewer there are.

London (AFP) – The Islamic State extremist group has executed 100 of its own foreign fighters who tried to flee their headquarters in the Syrian city of Raqqa, the Financial Times newspaper said Saturday.

An activist opposed to both IS and the regime of Syrian President Bashar al-Assad, who is well-known to the British business broadsheet, said he had “verified 100 executions” of foreign IS fighters trying to leave the jihadist group’s de facto capital.

IS fighters in Raqqa said the group has created a military police to clamp down on foreign fighters who do not report for duty. Dozens of homes have been raided and many jihadists have been arrested, the FT reported.
