Islamic militant group Islamic State has released a blanket call to violence against the citizens of countries planning military action in Iraq.

In the new video, titled “Indeed Your Lord Is Ever Watchful", the group’s chief spokesman, Muhammad al-Adnani, urged Muslims to take violent action against "disbelievers".

"If you can kill a disbelieving American or European — especially the spiteful and filthy French — or an Australian, or a Canadian, or any other disbeliever from the disbelievers waging war, including the citizens of the countries that entered into a coalition against the Islamic State, kill him in any manner or way however it may be."

The chilling message also harbours apocalyptic tones, declaring that soldiers of Islamic State (IS) should “be ready for the final campaign of the crusaders. Yes, by Allah's will, it will be the final one."

IS militants released the statement on Monday, shortly after the US carried out further air strikes against the group in Iraq over the weekend.

Blair on air strikes

Former British Prime Minister Tony Blair has revealed his support for British intervention in Iraq. The revelation coincides with the soon-to-be-made decision by Prime Minister David Cameron as to whether Britain will join the US and France in launching air strikes against IS in Iraq.

“We’ve got absolutely no choice but to do this,” Blair told CNN. “Not only to contain and destroy Isis, but to send a very strong signal to other terrorist groups in the region.”

During the interview, Blair also said air strikes alone may not be enough to defeat the terrorist group, urging Britain not to rule out sending ground troops to Iraq. “You cannot uproot this extremism unless you go to where it originates and fight it.” he said.

Cameron has repeatedly stated that he will not consider sending ground troops to the region. However, he has indicated that the UK may join the coalition’s air campaign to fight IS in Iraq.

The decision made by Cameron will undoubtedly be influenced by recent threats made by IS to innocent civilians both in Britain and abroad.

A few weeks ago IS militants revealed their intention to execute yet another British civilian, Alan Henning, captured in December 2013. The threat made to the former Salford taxi driver- turned - Islamic Aid worker has amplified public outcry over the atrocities being committed by the group.

Henning’s wife has appealed directly to IS on multiple occasions, asking that they spare her “peaceful and selfless” husband. Members from the Sharia Council in London have also joined the appeal, warning the militant group that the execution of Henning would be forbidden under Sharia Law.

Islamic state advance assault on Syrian Kurds

The increased threat of IS to the west has been accompanied by the group’s intensified offensive in northern Syria.

As a result, over 130,000 Kurds have fled to the nearby Turkish border, amidst Islamic State’s advancement towards the northern town of Kobani, the third largest Kurdish hub in Syria.

In the past week, IS extremists have seized dozens of villages and seem to be advancing northwards at an exponential rate. As a result, the UN refugee agency UNHCR said it expected hundreds of thousands of further Kurdish refugees to flee across the border in the coming weeks.

So far, Turkey has refused to involve itself in the US-led coalition against IS, as involvement posed a significant threat to the safety of dozens of Turkish hostages held by the group in Mosul. However, since the hostages were released unharmed on Sunday, Turkey’s President, Recep Tayyip Erdogan, has signalled that he may re-evaluate the country’s position in the global fight against Islamic State.
