They're the ultra-Nationalist swastika-loving battalion which is openly against the ceasefire in E. Ukraine.
Now extremists from the Azov unit, a far-right neo-Nazi militia defending the port city of Mariupol in southeastern Ukraine, are teaching children as young as six how to fire guns in an attempt to entice them into the country's bloody conflict.
Disturbing pictures have emerged from a military summer camp held on the outskirts of Kiev which show members of the voluntary group teaching so-called 'Azovets' how to behave as young fighters.
The children - which include girls and boys, some as young as six - are seen loading their guns, before taking part in exercises in which they crawl along the ground and fire at the enemy.
The camp comes under the command of Andriy Biletsky, who once admitted that the battalion 'do not like ceasefire at all'. The Azov men use the neo-Nazi Wolfsangel (Wolf’s Hook) symbol on their banner and several members are white supremacists or anti-Semites.
