A New Zealander dubbed the "bumbling" extremist can expect little help from his homeland after being captured in Syria by forces fighting the "Islamic State of Iraq and Syria" (ISIS), Prime Minister Jacinda Ardern warned Monday (March 4th).

Mark Taylor, 42, told the Australian Broadcasting Corporation he spent five years with ISIS but fled in December and surrendered to Kurdish forces because conditions had become unbearable, AFP reported.

"There was no food, no money, basic services were pretty much collapsed," he said from a Kurdish prison. "I was in a pickle myself and had to make a final decision, which was to leave."

Taylor earned his derogatory nickname in 2015 after sending out a series of pro-ISIS tweets but forgetting to turn off the geo-tagging function, giving away his location. He told the ABC the bungle earned him 50 days in an ISIS prison.

He also burned his New Zealand passport in a propaganda video and urged extremists in Australia and New Zealand to "commence operations".

Prime Minister Ardern ruled out stripping Taylor of his New Zealand citizenship.

Justice Minister Andrew Little said if Taylor returned, he could probably expect to face charges under anti-terror laws.
