Russia's planting mines everywhere, even cruelly hiding explosives in everyday items like fridges, toys, and children's books, Ukrainian military engineers say

• Russian soldiers who previously occupied Ukrainian territory left it littered with land mines. 
• Ukrainian military engineers told Insider that Russia also set deadly booby traps in people's homes.
• Moscow's troops hid explosives in every items like toys, fridges, and even children's books. 

Ukraine has been battling Russia's invasion for more than 17 months, but it's held it's own and even managed to liberate massive swaths of land that it lost early in the fighting. By some Western estimates, around 50 percent of what was initially seized has already been reclaimed by Kyiv's troops.
