Afghan Taliban warns jihadists to avoid Islamic State extremism

Statement urges fighters in Iraq and Syria to unite and refrain from judging others without evidence, in latest sign that advance of Abu Bakr al-Baghdadi’s group is unnerving other jihadist groups.

The Taliban has issued a statement directed at fighters in Iraq and Syria warning them against extremism in a clear rebuke to the Islamic State and its caliphate.

It calls on jihadists to remain united and not to judge others without evidence in what appears to be the latest tussle between Islamist groups for supremacy in their global fight.
