BAGHDAD — Iraqis on Tuesday celebrated the biggest victory against the Islamic State since the extremist group seized chunks of their country last year: The recapture of Ramadi's city center.Some people created traffic jams driving back into the heavily bombed-out city. Others flooded the streets of Baghdad and elsewhere in the country, carrying Iraqi flags and portraits of Iraqi military leaders and shooting off fireworks. The jubilation reflected a yearning to beat back the extremists that had been pent up for months.
