ISIL, a radical Sunni militant group, is considered to be one of the major threats to global security.
Over the last three years, the extremists managed to seize large swaths of land both in Iraq and Syria. The jihadists are also trying to spread their influence to North Africa, particularly Libya.
According to various estimates, the area controlled by the ISIL group reaches 90,000 square kilometers (34,700 square miles). Data on the number of ISIL followers also range from 50,000 to 200,000 fighters.
