"How cold-hearted, how coward one has to be to plant oneself in front of a refugee bus, to swear and to roar in order to scare the people sitting inside, among them several women and children," government spokesman Steffen Seibert said during a regular news conference, as reported by Reuters.
On Thursday night a group of about 100 people blocked the entry to a refugee shelter in Clausnitz, a small town in Germany's eastern state Saxony.
Video footage posted online shows the crowd surrounding the bus with the refugees inside, yelling slurs and hindering the refugees from getting off.
Over the weekend, a ready-to-move-in shelter for asylum seekers was set ablaze in the city of Bautzen, also in Saxony, with several spectators applauding and some hindering the work of firemen.
