Takako Arai's earliest memories are of Tsukiji, playing hide-and-seek with her brother in the concrete maze of Tokyo's sprawling fish market. Years later, she now runs the family's seafood stall that sells mackerel and yellowfin tuna. Arai and hundreds of other fish traders are reluctantly packing up and preparing to leave Tsukiji this week for a gleaming new $5 billion market on reclaimed land farther from central Tokyo. "I feel torn. I grew up here and I feel like we're losing so much of our history by leaving this place," said Arai, 45. The 83-year-old market, a popular tourist attraction, is a warren of shops and warehouses where small turret trucks zip around laden with ice-filled boxes of fish. But city officials say it has become dilapidated and unsanitary. REUTERS/Issei Kato SEARCH "TSUKIJI CLOSES" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES. TPX IMAGES OF THE DAY.

It was an awkward coalition riven by political and sectarian differences, facing an elusive, fanatical enemy dug into an urban maze of narrow streets and alleyways. So, could Iraq's government really deliver on its vow to vanquish Islamic State? In the end, the army, Shi'ite Muslim paramilitaries and Kurdish Peshmerga fighters mustered rare unity to end Islamic State's reign of terror in Iraq's second city Mosul, the seat of the ultra-hardline Sunni insurgents' "caliphate". Baghdad's victory in July 2017 after nine months of fighting was the coup de grace for the caliphate and came three years after a jihadist juggernaut seized one third of the Iraq. But even with supportive U.S. air strikes, Baghdad's triumph came at a devastating cost for the once-vibrant, multicultural city in northern Iraq and the surrounding region.
