Ukrainian troops in Mariupol are taking ammunition off of Russian troops and smuggling in weapons to resupply and hold out against the Russian assault. Western officials in a briefing to reporters Tuesday said there is evidence of Ukrainian troops in Mariupol smuggling weapons into encircled areas for reinforcement as additional Russian troops close in. "Ukrainian forces, though remarkably adept at smuggling weapons into areas which are encircled, they are also largely being able to resupply their fighters by taking weapons, ammunition, off Russian soldiers in the city itself," Western officials told reporters in a briefing.
