Inside an ISIS suicide-bombing truck

These are the massive machines used by Islamic State to blow their targets to bits.

A Brisbane “rebel” fighting against ISIS in the Middle East has uncovered a key hideout during a raid that shows the extent of the terror group’s deadly armory and their sinister tactics when using suicide trucks.

Ashley Dyball, who goes under the alias Mitchell Scott, has been fighting alongside the Kurdish People’s Protection Group (YPG) since May, when he revealed to family and friends he was off to the “front line tomorrow #f***isis.”

“Why I left: Because I couldn’t sit around any longer watching innocent women and children being raped and slaughtered Isis [sic] is a cancers [sic] and needs to be destroyed before it spreads any further,’’ he wrote.

Since then, he has been working with the group to reclaim battle zones claimed by IS in what he describes as “humanitarian work.”

In chilling posts earlier this week, Dyball uploaded images showing bunkers used by the group to hide during allied air raids, and the arms the group has at its disposal.

The Coalition of Syrian Democratic Forces — a collaboration of Kurdish, Syrian and Assyrian forces and backed by the US-led international coalition — fought ISIS in a deadly, two-week battle to reclaim the city of al-Hawl last week, an important site for the radical group thanks to its strategic location on the Syrian-Iraqi border.

“Our forces were able to liberate the key town of al-Hawl from the terror group after heavy battles,” SDF fighter Shoresh Hisso told ARA News.

“Our operations caused heavy losses in the ranks of Daesh (ISIS), forcing the remaining terrorists to escape.”

A day after announcing Dyball and his Kurdish counterparts had joined the efforts to reclaim al-Hawl, the 23-year-old uploaded images of a dug-out tunnel from the Al-Hasakah Governorate in northeastern Syria, which Dyball described as “well structured.”

A few hours later, he posted an album highlighting the massive armor-plated suicide trucks the group uses in attacks, packed with 10 tons of explosives in 20 large barrels.

Built to act like a tank, the “homemade” truck is fortified by sheets of metal in a bid to protect the driver from an enemy attack before the vehicle reaches its target destination.

In the back lies a plethora of improvised explosive devices designed to take out its enemies in one terrifyingly fell swoop.

Earlier this year, Immigration Minister Peter Dutton warned Dyball would either die fighting ISIS or face jail if he returned home, but support for the foreign fighter is growing. His Facebook page is filled with “hero” messages from back home.

“The work he’s doing there, some of it’s very dangerous,” “60 Minutes Australia” reporter Tara Brown, who visited Dyball for a piece that aired earlier this month, told news.com.au.

“He’s clearing landmines, making villages safe for people to return to. He’s very much driven by the fact that there’s no one else helping. He feels driven to help. He sees the threat, he sees what he’s doing there in helping the Kurdish people and he’s helping [to keep] the threat from coming to Australia.”
