US President Barack Obama has declared war on Islamic State (ISIS), saying that it "misrepresents Islam." 

But video footage which surfaced earlier this week proves otherwise - and that ISIS may be gaining ground in new places in the Arab world. 

The Ansar al-Sharia terror group, affiliated with ISIS, has declared authority during the last several days over the coastal city of Darna, Libya.

Darna, while seemingly any other city in northern Africa, is located strategically between Benghazi and the Egyptian border - just 289 km (179 miles) and 333 km (206 miles), respectively.

As the footage below reveals, hundreds of armed terrorists brandishing machine guns held a parade of force in Darna, calling for residents to gather in the town square for the declaration of allegiance to ISIS.

Libya has been embroiled in an ongoing civil war since the fall of dictator Muammar Ghaddafi in 2011. More recently, several terrorist organizations affiliated with the Ansar al-Sharia movement - and, by proxy, ISIS - launched a campaign against the Libyan government in Tripoli on July 13. Thousands have died in the clashes. 

This is not the first terror organization abroad to declare loyalty to ISIS - either formally or informally.

In the Sinai Peninsula, the Ansar Bayt Al-Maqdis group - which has been waging an ongoing war with the Egyptian Army - has been staging ISIS 'copycat' beheadings and is thought to have declared de facto loyalty to the group. 

ISIS has stated on multiple occasions that it wishes to see "the whole world" under a terror reign, including the West and Israel
