Brazilian model, sniper killed by Russian forces in Ukraine PHOTO/VIDEO

A Brazilian model and sniper has been killed by a Russian missile strike in Ukraine just three weeks after she joined the fight against Putin's forces.

Thalito do Valle, 39, took part in humanitarian missions around the world and had previously fought against ISIS in Iraq, per Daily Mail.

She was killed last week after a missile struck her bunker in Kharkiv, the north-eastern city which has been subjected to intense bombardment throughout the war.

The attack also killed former Brazilian Army soldier Douglas Burigo, 40, who returned to the bunker to find Thalita.

She was the only troop member left behind after the first missile strike took place, according to other fighters.

Thalita documented her conflict experience on her YouTube channel where her videos on fighting ISIS gained her 32,000 views.

She previously studied law after working as a model and actress in her youth and has participated in animal rescues with NGOs.
