Iraqi Shiite fighters from the Popular Mobilisation units deploy in the city of Baiji, north of Tikrit, as they fight alongside Iraqi forces against the Islamic State (IS) jihadist group to try to retake the strategic town for a second time, on June 9, 2015. Baghdad regained control of Baiji -- located on the road to IS hub Mosul and near the country's largest oil refinery -- last year, but subsequently lost it again.

PALEMBANG, SOUTH SUMATRA, INDONESIA - OCTOBER 02: A firefighter holds a water pipe as they extinguish the fire on burned peatland and fields at Sungai Rambutan village, Ogan Ilir district on October 2, 2015 in Palembang, South Sumatra, Indonesia. The air pollution or haze has been an annual problem for the past 18 years in Indonesia. It's caused by the illegal burning of forest and peat fires on the islands of Sumatra and Borneo to clear new land for the production of pulp, paper and palm oil. Singapore and Malaysia have offered to help the Indonesian government to fight against the fires, as infants and their mothers are evacuated to escape the record pollution levels.
