DONETSK, Ukraine (AP) — Almost two weeks after Malaysia Airlines Flight 17 was blown out of the sky, the remains of some passengers are feared rotting in the 90-degree (32-degree Celsius) midsummer heat, deepening the frustration of relatives desperate to recover the bodies of their loved ones.

Fighting between Ukrainian forces and separatist rebels has kept away international police charged with securing the site, a sprawling area of farmland and villages. And until it’s secured, there is no way for forensic experts to gather up any remaining bodies or collect debris for analysis.
