One of the injured passengers of a regional plane, which crashed last week in Western Siberia, died on early on Thursday in a hospital, local health authorities said.
The UTair ATR 72 plane crashed on April 2 on a takeoff from Tyumen airport. Thirty-one people died in the crash and twelve survived but were severely injured.
The deceased patient of a hospital in Tyumen has been identified as Lyudmila Volkova.
The surviving 11 passengers are still hospitalized.
Six of them remain in a serious condition and one is in a critical condition at an intensive care unit in a hospital in Tyumen.
Three other survivors, who are in a stable condition, are being treated at the same hospital.
One air crash survivor is in a Moscow hospital. His condition is also stable, doctors say.
Investigators said soon after the incident that failure to deice the aircraft was most probably a factor in the disaster.
