An eighteen-year-old Ukrainian woman has died in hospital, weeks after a brutal sexual assault that prompted a campaign against political corruption.
Oksana Makar was attacked in the southern city of Mykolayiv on 8 March by three men who raped her and tried to strangle her before setting her alight.
Three men were arrested, but two - whose parents had political connections - were released without charge.
They have since been re-arrested, after the case prompted a national outcry.
Interior ministry spokesman Volodymyr Polischuk told a news conference on Thursday that all three men, aged 22 to 24, now faced charges of rape and murder. He said they could face life sentences in jail.
Ms Makar lost consciousness after her attackers abandoned her at a construction site and set fire to her.
She was eventually found the next morning by a stranger and taken to hospital in Mykolayiv with 55% burns.
She was transferred to a specialist unit in the eastern city of Donetsk because of the severity of her burns and damage to her lungs.
Doctors at the hospital's burns centre said her heart had stopped because of bleeding in her lungs and she died after repeated attempts to resuscitate her.
Interior Minister Vitaly Zakharchenko has stated that the parents of two of the suspects are former government officials in the Mykolayiv area.
Ukrainian media have shown footage of one of the three suspects describing to police how Ms Makar was attacked in a flat in the city and then wrapped in a blanket and left in a pit.
The victim's mother posted a video of her lying in her hospital bed, in which some of her appalling injuries were visible.
The Kiev Post described the attack as "one of Ukraine's most heinous crimes in recent years".
There have been several protests in Mykolayiv and elsewhere in Ukraine, including Odessa, Lviv and Kharkiv.
The case has led to the Communist Party, which is part of the ruling coalition in parliament, to highlight its call for a return to the death penalty.
