of whom there are quite a few, people have ways of either paying, it's a relatively corrupt system. we heard stories unable to corroborate them, but of people paying money per month to avoid service. the border there between initially ukraine and hungary, but where we were, ukraine and romania, that's the river tisa, which is a relatively fast flowing river. it's very cold, obviously, in winter with full of snowmelt. so it's pretty dangerous to swim across in certain places. and obviously, the ukrainian border guard are trying to stop people leave. there's one figure from the ukrainian border guard that they're detaining 20 people a day trying to cross that or other borders or coming through the mountains. how many people are we talking about, do you estimate? we turned to the ukrainian military to ask.
