Shi'ite fighters launch a rocket during clashes with Islamic State militants on the outskirts of al-Alam March 8, 2015. Thaier Al-Sudani: “It was me and a few other Iraqi journalists working for local outlets. We went to the frontlines in coordination with the Iraqi government forces and supporting militias. The press officer would come in the morning and take us to the frontline in a convoy. Whenever an area was won from Islamic State, the fighters would chant and pray and show victory signs. Most of the areas we were in didn't have residents, so after the battle they would resemble ghost towns; nothing but burnt cars and charred bodies of Islamic State fighters. Al-Alam was an exception as it had some residents who chanted for the government forces after their victory”. (Photo by Thaier Al-Sudani/Reuters)
