New Delhi: Al-Qaida chief Ayman al-Zawahiri in an audio interview has called upon his fighters to take Western hostages and exchange them for Jihadists who have been imprisoned, the monitoring service SITE Intelligence Group said on Sunday.

In a recording posted online, Al-Zawahiri called on the global militant network to kidnap Westerners “until they liberate the last Muslim male prisoner and last Muslim female prisoner in the prisons of the Crusaders, apostates, and enemies of Islam,” according to SITE.

However, the authenticity of the recording has not been verified yet.
