Islamic State News Update - With each passing day, it is becoming clear to several world leaders that US President Barack Obama's warning about defeating ISIS fighters will be a long-term plan. With the recent video released, the Islamic State militants vowed to never stop the violence and hostilities.

News broke out about the latest Islamic State propaganda video showing a 17-year-old Australian teenager speaking to deliver a message especially to Prime Minister Tony Abbott and US President Barack Obama. According to ABC AU, the Australian Security agencies believed the boy is Abdullah Elmir.  

ABC News said Abdullah Elmir, a 17-year-old Australian who uses the alias Abu Khaled, went missing from his home in Sydney's west at the end of June. He disappeared together with another 16-year-old Australian boy. The pair is believed to travel to Turkey and then crossed the border into Syria to join Islamic State militants.

In the latest ISIS video, the speaker, Abdullah Elmir delivered a message particularly mentioning Australia and the nation's Prime Minister Tony Abbott.

"To the leaders, to Obama, to Tony Abbott I say this: these weapons that we have, these soldiers, we will not stop fighting, we will not put down our weapons until we reach your lands, until we take the head of every tyrant and until the black flag is flying high in every single land," he said.

Abdullah Elmir also said ISIS militants would fight until its infamous black flag was flying over the White House and the Buckingham Palace.

"Bring every nation that you want to come and fight us. It means nothing to us. Whether it's 50 nations or 50,000 nations, it means nothing to us," he continued. "Bring your planes. Bring everything you want to us. Because it will not harm us. Why? Because we have Allah."

Prime Minister Tony Abbott said through a statement the video underscored Islamic State threats.

"ISIL is a threat that reaches out to Australia and our allies and partners," Abbott stated. "That is why Australia has joined the Coalition to disrupt and degrade ISIL in Iraq and is giving our law enforcement and security agencies the powers and resources they need to keep Australia and Australians as safe as possible."

International Business Times said Australia is participating in the US-led global coalition against the Islamic State and its fighter jets are carrying out airstrikes to fight the jihadists in Iraq and Syria.

Meanwhile, the Islamic State has grabbed the world's attention after they released four brutal decapitation videos of their hostages. The news of their viciousness and brutality has instigated fears globally.

On separate news, Wall Street Journal reported defeating the Islamic State militants will happen only in phases. The US administration progressively pronounced the struggle as one that will develop in phases, instead of something approaching one grand sweep.

Aside from Islamic State's cruelty, the task to destroy them is complicated. Any plans for defeating the jihadists reels together numerous large challenges and they aren't going to be engaged in all at once. To attack ISIS without adequate support to see the fight through victory is to invite vicious retributions from the Islamic State insurgents in the future.

On the other hand, news about Islamic State's brutality continues after a video had circulated online by Syrian activists showing the extremists from the hardline militant group pelting a woman to death in Syria's western countryside of Hama.

The Huffington Post reported that in the video, a veiled woman accused of adultery pleads her father for forgiveness, which he refuses. Before being tied up with a rope and directed to a grave-like hole in the ground, the woman is asked if she takes her fate. She submissively agrees. Bending in the hole, she begins to pray out loud. The fighters and the man believed to be her father brutally stone her with large rocks until she is motionless.

While the video appears to be new to social media, the WorldPost could not independently verify the video's authenticity. The Syrian Observatory for Human Rights said on Tuesday it could not corroborate the date of the said video.

The Islamic State has been accused of many crimes against humanity. And they continue to make headline news because of their unending cruelties. Several Muslim leaders around the globe may have condemned the ISIS' actions but defeating them is never easy and would never be just an overnight scheme.
