MOSCOW - One more passenger of the Tu-154 plane that made an emergency landing in Moscow's Domodedovo airport died in hospital late Saturday, raising the death toll of the accident to three, local media reported citing a source.

According to the source from Dagestan, the North Caucasus republic, the third victim was Dagestan president's brother Gadzhimurad Magomedov, who had got serious injuries during the emergency landing.

"His seat was in the first class, close to the cockpit. He was hurt badly and died in hospital," the source was quoted as saying by RIA Novosti news agency.

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.
