Earlier on Saturday, the Dagestani president Magomedsalam Magomedove told reporters that his brother was among the injured passengers.

The Dagestan Airline plane, en route from Moscow to Dagestan's capital Makhachkala, was forced to make the emergency landing due to engine failure after it took off from Moscow's Vnukovo airport Saturday afternoon.

During the landing, it skidded off the runway, crashed into a small hill and broke into three parts. So far, three people were killed and over 80 people were injured.
