Late last week, RAF warplanes launched their first bombing raids on Syria
, targeting the Omar oilfield in the eastern part of the country. The extensive oil infrastructure across Syria and Iraq has made the so-called Islamic State one of the richest terrorist organisations
in history, providing the group with an estimated $500 million every year, according to a recent Bloomberg report
Kidnap and ransom bring in an estimated $45 million each year while foreign donations are worth approximately $5 million. One of the so-called Islamic State's most important resources is seldom mentioned and that's farmland. Fertile agricultural territory controlled by the group across Syria and Iraq could potentially generate over $200 million every year, according to a Thomson Reuters report.
