Large number of concrete blocks being constructed to hinder military vehicles in key locations, UK says
Russia is stepping up its efforts to build substantial obstacle barriers to slow the advance of Ukrainian forces in key locations it is defending, including around the devastated city of Mariupol, the UK Ministry of Defence has said.
Its intelligence assessment on Tuesday said the Russian military was using two plants in occupied Mariupol to produce large numbers of “dragon’s teeth” – pyramidal concrete blocks designed to slow advancing military vehicles.
