IS leader Baghdadi calls on militants to 'resist enemies' in purported new audio

In his first alleged message in nearly a year, and following reports of his possible death, the elusive jihadist leader called on his supporters to target the "media centres" of countries fighting his group.

"The leaders of the Islamic State and its soldiers have realised that the path to... victory is to be patient and resist the infidels whatever their alliances," the speaker said.

It was not clear when the message, released by the IS-affiliated Al-Furqan media group, was recorded.

In it, he lashed out at "infidel nations headed by America, Russia and Iran" who, along with their allies, have inflicted losses on the jihadists during separate offensives against IS in Syria and Iraq.

"We will remain, we will resist and be patient... We will not give in," he said, a day after Iraqi forces defeated IS fighters who had seized areas in a surprise offensive around Ramadi west of Baghdad.

The apparent IS leader called on "soldiers of the caliphate" to pursue their "jihad", or holy war, and attacks.

He urged his followers to "target the media centres of the infidels", without providing further details.

A US intelligence community source said they were examining the audio message.

"We are aware of the audio tape purported to be of Abu Bakr al-Baghdadi and are taking steps to examine it," the source said in a statement.

"While we have no reason to doubt its authenticity, we do not have verification at this point."

Thursday's was the first audio message said to be of Baghdadi since November 2016, when he spoke in a defiant tone in urging his supporters to defend the city of Mosul against a massive operation by Iraqi forces.

That recording, also released by Al-Furqan, was a rare sign of life from Baghdadi.

In July, Moscow said it was struggling to confirm if Baghdadi was dead or alive, a month after reporting his possible demise in a May air strike near the one-time IS stronghold of Raqqa in Syria.

With a $25 million US bounty on his head, Iraq-born Baghdadi has successfully avoided an intense effort to seek him out for six years or more.

Rumours have abounded about Baghdadi's health and movements, but his whereabouts have largely remained unclear.
