"We were very shocked by the news of the tragedy that killed a large number of passengers and crew members.
It is hard to find words of comfort for families and friends of the victims, but I am confident that you will find strength and give support to those who have lost their loved ones.
On behalf of the Serbian government, citizens of Serbia and in my personal name I extend deepest sympathy to the families of the victims, to you and the highest leadership of the Russian Federation," reads the letter of Prime Minister Brnabic.
