A Chechen militant has complained that Saudi jihadis are favouring their own friends and family for bombing missions.
Kamil Abu Sultan ad-Daghestani said fighters were becoming increasingly angry after being left languishing on the waiting list for months.

Amir [Leader] Akhmed al-Shishani told me about a young lad who went to Iraq for a suicide mission and he went there because in Sham [Syria] there is a veeeeery long queue [of several thousand people],' he wrote.
He said the fighter eventually gave up after three months and returned to Syria
