The term 'PART OF ISIL' can be solved by the 6-letter word 'LEVANT'. The LEVANT is a geographical region in the Eastern Mediterranean, which includes parts of modern-day Syria, Lebanon, Jordan, Israel, Palestine, and Cyprus. It is an area that has been historically significant to many cultures and religions, including Christianity, Judaism, and Islam. In recent years, it has become a major battleground for the Islamic State of Iraq and the LEVANT (ISIL), a militant group that seeks to establish a caliphate in the region.
