Al-Qayyara, Iraq (CNN) Menacing black smoke hangs over the town of al-Qayyara. The air here is poison. Children with blackened hands and soot-stained faces play beneath the toxic plumes. The early afternoon sun is so eclipsed by the haze that day seems like endless twilight. The dark filth coating the landscape and choking residents' lungs comes from oil wells sabotaged and set alight by ISIS in August. Engineers and firefighters have been battling the flames for 100 days now. When CNN first visited al-Qayyara back in early October, they had tackled six fires with nine to go. But the real extent of the damage had yet to be determined.Town of al-Qayyara, south of Mosul, is awash with toxic plumesISIS set oil wells ablaze in bid to hamper Iraqi forces from advancingWhile several battle to quell fires, residents breathe poisonous fumes

(CNN) -- Novak Djokovic matched Roger Federer's feat of three successive titles at the Dubai Tennis Championships by crushing the world No. 2 in Saturday's final. The Serbian, who also beat Federer in the Australian Open semifinals last month on the way to winning his second grand slam, triumphed 6-3 6-3 in one hour and 11 minutes to clinch the 20th ATP Tour crown of his short career. The 23-year-old, seeded second, claimed the $386,000 first prize as he denied his Swiss opponent a fifth title in Dubai and 68th overall. "Any time I win against Roger it's a great success because he's such a great player. We all know how mentally strong of a player he is," Djokovic, who trailed 3-1 in the second set, told the ATP Tour website.Second seed Novak Djokovic beats Roger Federer 6-3 6-3 in Dubai finalSerbian wins the event for the third year in a row to match Swiss opponentFour-time winner Federer has now been beaten twice in Dubai finalsWomen's No. 1 Caroline Wozniacki beaten in Qatar final by Vera Zvonareva

Morgan Parra can spark a revolution among France's forwards to inflict a second quarter-final defeat on New Zealand in Cardiff in eight years, according to Philippe Saint-Andre. France boss Saint-Andre defended dropping trusted half-back Sebastien Tillous-Borde in favour of Parra by accepting his pack need to be bossed about after their feeble showing in 24-9 defeat to Ireland. Les Bleus stunned New Zealand 20-18 in Cardiff in 2007, with Saint-Andre admitting only a return to classic French free-running rugby will afford the chance of a repeat.
