Russian-Ukrainian war veterans and relatives of the dead soldiers have gathered at the square.

About 100 people have paid tribute to the victims with the singing of the Plyve Kacha po Tysyni Ukrainian Lemko sorrow song, which became a symbol of mourning for those who were killed on Kyiv's Independence Square during the Revolution of Dignity and during the war in Donbas.

As UNIAN reported earlier, after fierce fighting late in August 2014, Ukrainian servicemen participating in the Anti-Terrorist Operation (ATO) in eastern Ukraine were surrounded near the town of Ilovaisk in Donetsk region. The Russian military shot into the "live corridor," which, according to the agreement, was to be used by retreating Ukrainian soldiers. The Ukrainian army suffered heavy losses.

Only official figures state that 366 Ukrainian troops were killed and 249 were wounded. Additionally, 128 were captured, while 158 were designated as missing.

The Ukrainian parliament's ad hoc commission that has been probing the Ilovaisk tragedy estimates total losses of 1,000 Ukrainian troops during that battle. According to the military prosecutor's office, the number of separatist fighters with Russian regular troops during the fighting near Ilovaisk exceeded 16,000 men.
