Al-Qaeda’s leader has urged his followers and all militants in Syria to unite ranks and prepare for protracted jihad, or holy war.

Ayman al-Zawahri tells the militants to remain steadfast and change tactics to a guerrilla war. His remarks came in an audio message released on Monday by al-Qaeda’s media arm As-Sahab.

Al-Zawahri says an "international satanic alliance" will never accept Islam’s rule in Syria. He says the war isn’t an exclusively nationalist Syrian cause but a campaign by the entire Muslim nation that seeks to establish divine rule.

Al-Qaeda’s Syria branch - formerly the Nusra Front but now known as the Fatah al-Sham Front - has come under increasing attack from the US-led coalition in recent months and some of its most senior leaders have been killed in airstrikes.
