Kyiv, April 12 (UNI) Ukrainian President Volodymyr Zelenskyy has claimed that Russian troops have left mines everywhere, including in homes, fields and on the streets of the northern regions of his country. Zelenskyy in a late night address on Monday, accused the Russian troops of leaving behind large number of dangerous objects including tripwire mines. "Security work is underway in the northern regions of our country from where the occupiers were expelled...First of all, it is mine clearance. Russian troops left behind tens of not hundreds of thousands of dangerous objects. These are shells that did not explode, mines, tripwire mines." He further said that the Ukrainian troops are disposing these items daily. He said, "The occupiers left mines everywhere... In the houses they seized... Just on the streets, in the fields. "They mined people's property, mined cars, doors... They consciously did everything to make the return to these areas after de-occupation as dangerous as possible". The Ukrainian president also said that Ukraine is now one of the most contaminated by mines in the world due to Russia's actions and urged the international community to consider this asa war crime of Russian troops. He said that Russian troops would not have done this without the appropriated orders. "They deliberately did everything to kill or maim as many of our people as possible, even they were forced to withdraw from our land... without the appropriated orders, they would not have done it," he said. "The 47th day of the Russian-Ukrainian war, this shameful invasion that is gradually wiping Russia out of international relations, is coming to an end. Invasion that makes it more and more toxic every day. Now it is only a matter of time before the Russian army with its own actions and war crimes forces everyone in the world to renounce all ties with the Russian Federation". UNI VP RNJ
