In a sign the Islamic State terror group could be pressed for cash, a new report claims its leaders slashed the salaries of all its fighters in half.

The "Treasury Ministry" of ISIS blamed "exceptional circumstances," The Jerusalem Post reported.

The terror group reportedly did not explain exactly what those circumstances were. However, the announcement came out in December, before the Pentagon revealed that a January airstrike took out an ISIS cash stockpile in Mosul, Iraq.

Terror leaders said this would not affect the collection and distribution of Zakat, a religious tax benefitting the poor, the Post adds.

Treasury minister Bayt al-Mal reportedly cited the Koran, which prioritizes "jihad of wealth," or spending in beneficial or charitable ways, over "jihad of soul."
