A Russian transport helicopter has been shot down in Syria, killing all five people on board, a Kremlin spokesman said.
The Mi-8 helicopter was shot down in Idlib province while returning to the Russian air base on Syria's coast after delivering humanitarian goods to the city of Aleppo, the defence ministry said.
The helicopter had three crew members and two officers deployed with the Russian centre at the Hemeimeem air base on board.
Dmitry Peskov, spokesman for Russian president Vladimir Putin, said that "from what we know from information provided by the defence ministry, all those who were on the helicopter died".
He said the Russians "died heroically because they tried to move the aircraft away so as to minimise losses on the ground".
