Some 28,000 people have fled the Tikrit area as Iraqi forces battle the Islamic State jihadist group in a massive offensive aimed at retaking the city, the UN said.The involvement of Shiite militiamen in the operation, which has been dubbed an attempt to avenge the IS massacre of hundreds of mainly-Shiite recruits last year, has raised fears of sectarian killings targeting Sunni Arabs.
“Military operations in and around Tikrit have precipitated displacement of an estimated 28,000 people to Samarra,” the UN said in a statement on Saturday. “Field reports indicate that additional displacements are under way and that yet more families remain stuck at checkpoints,” it said. The newly displaced Iraqis join what the International Organization for Migration says are 2.5 million people already forced from their homes in the country.
