Al Fallūjah

Following the 2003 invasion of Iraq, which triggered the Iraq War, the city became a major centre of resistance during the insurgency. The United States, the United Kingdom, and the Iraqi Interim Government twice engaged in fierce urban combat with insurgents throughout the city; the first battle of Fallujah failed to dislodge the insurgents, triggering the second battle, in which the coalition forces successfully took control of the city. However, heavy fighting from these two battles left the city severely damaged, though it remained occupied by the coalition until 2011. In January 2014, three years after the American withdrawal from Iraq, Fallujah was captured by the Islamic State of Iraq and al-Sham (ISIS) and suffered a major population decline.
